Turnbuckle Manufacturers General Hardware Rigging Heavy Duty Wire Rope Turnbuckle Eye-Hook Wire Rope Turnbuckle The company recently exported a large number of turnbuckle to Europe and America The turnbuckle screw is a type of fastening device that is commonly used in various applications, such as construction, rigging, and engineering. It consists of a long metal rod with screw threads on either end, and a central body that can be adjusted to increase or decrease the tension. The turnbuckle screw is designed to connect two objects or structures together, while allowing for easy adjustment of the tension. It is often used in applications where there is a need to tighten or loosen the connection periodically, such as in the installation of cables, wires, or chains. To use a turnbuckle screw, the two objects or structures to be connected are typically fitted with eye bolts or hooks at each end. The turnbuckle screw is then inserted through these attachment points, and the central body is rotated to either increase or decrease the tension. This rotation causes the screw threads to move in or out, effectively pulling the objects closer together or pushing them apart. The turnbuckle screw is made from high-strength materials, such as steel or stainless steel, to ensure its durability and resistance to corrosion. It is available in various sizes and configurations to accommodate different load capacities and application requirements. Overall, the turnbuckle screw provides a reliable and adjustable connection solution in a wide range of industries and applications.

It is characterized by a wide variety of specifications, performance uses vary, and standardization, serialization, generalization of the degree is also extremely high. Therefore, some people also have a national standard for a class of fasteners called standard fasteners, or simply referred to as standard parts. Application of fasteners In a variety of machinery, equipment, vehicles, ships, railroads, bridges, buildings, structures, tools, instruments, meters and supplies, etc., can see a variety of fasteners. It is characterized by a wide variety of specifications, different performance uses, and standardization, serialization, generalization of the species degree is also extremely high. Therefore, some people also have a national standard for a class of fasteners called standard fasteners, or simply referred to as standard parts. Fasteners are widely used in the mechanical foundation parts. With China's accession to the WTO in 2001 and step into the ranks of international trade powers. China's fastener products are exported to a large number of countries around the world, and fastener products from all over the world continue to pour into the Chinese market. Fasteners as one of the products with large import and export volume in China, to achieve international convergence, to promote Chinese fastener enterprises to the world, to promote fastener enterprises to fully participate in international cooperation and competition, are with important practical and strategic significance. As each specific fastener product specifications, dimensions, tolerances, weight, performance, surface conditions, marking methods, as well as acceptance inspection, signs and packaging and other items of specific requirements. Commonly used testing instruments The most important aspect of the development and design of fasteners is quality control, and there are several major gates from incoming materials to finished product shipment, which have different inspection methods. First of all, the incoming material is related to the appearance, size, elements, performance, harmful substances testing, etc.; the process is more appearance, size, knocking experiments, forging flow lines; heat treatment is more appearance, hardness, torque, tension, gold and so on; surface treatment is more some hydrogen embrittlement test, plating, salt spray, etc., including the shipment of a harmful substances testing. In the size, appearance testing, common is the secondary yuan, contour measuring machine, coordinate measuring machine, image sorting machine (this is a full selection machine); mechanical and chemical testing, mainly hardness machine (Rockwell and Vickers), tensile strength machine, metallographic microscope; materials testing, there is a spectral analyzer, salt spray tester.

Screws and bolts are two similar types of fasteners, usually made of metal, that are characterized by a spiral ridge called the external thread (external thread). Definition of thread: A thread is a shape with a uniform spiral thread projection on the external or internal surface of a solid . Screw means screw (foreign name: Screw), a tool that uses the physics and mathematics of beveled circular rotation and friction of an object to tighten the instrumental mechanism in a progressive manner. Screw is the generic term for fastener, everyday verbal language. The metric thread is measured in MM (millimeters), and it has a 60 degree tip angle. Both the American and Imperial threads are in inches. American threads also have a tip angle of 60 degrees, while imperial threads have a tip angle of 55 degrees. Bolt: A mechanical part with a cylindrical threaded fastener with a nut. A type of fastener consisting of two parts, the head and the screw (cylinder with external thread), which needs to be fitted with a nut and is used to fasten the connection of two parts with through holes. This form of connection is called bolt connection. If the nut is screwed off the bolt, and the two parts can be separated, so the bolt connection is a removable connection.

Screw is a general term for a fastener, a threaded fastener with various structural shapes. Screws include screws, bolts, studs, etc. According to the type of screw head, it can be divided into several common head types: pan head, round head, cylindrical head, countersunk head, flat head, semi-countersunk head, semi-round head, hexagonal head, spherical cylindrical head, etc. Different kinds of screws have their corresponding standards, and there are many types of slot types for screws, such as I-slot, cross slot, hexagonal, etc. Rarely, we see H-shaped, triangular, Y-shaped slot types, etc.

self-drilling screws connect components in one work step: they drill, form the thread and fasten. This reduces the installation time, saves tool changes and costs for drills. The self-drilling screws are completed by an optional pre-assembled sealing washer. self-drilling screws are available in stainless steel for weather-exposed areas and in zinc-plated steel for unweathered areas.

Various products of Bolt, providing product images and basic parameters with each Railway Bolt and Bolt; We are a professional Chinese manufacturer of Bolt, and look forward to your cooperation!

Self-drilling screws eliminate the need for a pilot hole, but can tap as well. Self-tapping screws tap their own threads, but cannot drill through metal and require a pilot hole. These screws are not interchangeable, and mixing up the two can cause many headaches or possible failures in the field.

Hexagon bolts are actually called a variety of methods. For example, they can be called hexagonal screws. For example, they can be called hexagonal screws. It can also be called a hexagonal bolt. This is the same meaning. It`s just that personal habits are different. The following creation of the screw manager Zhu introduced the basic knowledge of the hexagonal screw standard. 1. Ordinary bolts are divided into three types: A, B, and C. The first two are refined bolts and are less used. Generally speaking, ordinary bolts refer to Class C ordinary bolts. 2. Common C-class bolts are commonly used in some temporary connections and connections that need to be removed. Common bolts commonly used in building structures are M16, M20, and M24. Some mechanical industry rough bolts may be large in diameter and special in use. High-strength bolts 3. The material of the high-strength bolt is different from the ordinary bolt. High-strength bolts are generally used for permanent connections. Commonly used are M16~M30. The oversized high-strength bolts are unstable and should be used with caution. 4. The bolted joints of the main components of the building structure are generally connected by high-strength bolts. 5. The high-strength bolts shipped from the factory are not divided into pressure-bearing type or friction type. 6. What is the friction type high-strength hex bolt and the bearing type high-strength bolt? Actually, there are differences in design calculation methods: (1) Friction type high-strength bolts are slipped between the plates as the limit state of load carrying capacity. (2) The bearing type high-strength bolts are slipped between the plates as the normal use limit state, and the connection failure is taken as the limit state of the load capacity. 7. Friction type high strength bolts do not fully exploit the potential of bolts. In practical applications, friction-type high-strength screws should be used for important structures or structures subjected to dynamic loads, especially when the load causes reverse stress. In this case, the unutilized bolt potential can be used as a safety reserve. In addition to this, high-strength bolted connections should be used to reduce the cost. High strength bolts are different from ordinary bolts 8. Ordinary bolts can be reused, and high-strength bolts cannot be reused. 9. High-strength bolts are generally made of high-strength steel (45 gauge steel (8.8s), 20MmTiB (10.9S), which is a pre-stressed bolt. The friction type uses a torque wrench to apply the specified pre-stress, and the pressure-type type twists off the plum head. Ordinary bolt Usually made of ordinary steel (Q235), just tighten it. 10. Ordinary bolts are generally 4.4, 4.8, 5.6 and 8.8. High-strength bolts are generally grades 8.8 and 10.9, with 10.9 grades. 11. The screw holes of ordinary bolts are not necessarily larger than those of high-strength bolts. In fact, ordinary bolt holes are relatively small. 12. Ordinary bolts A and B screw holes are generally only 0.3~0.5mm larger than bolts. Class C screw holes are generally 1.0 to 1.5 mm larger than bolts. 13. Friction type high strength bolts transmit load by friction, so the difference between screw and screw hole can reach 1.5~2.0mm. 14. The standard transmission force characteristic of the pressure-bearing high-strength hex bolt is to ensure that the shear force does not exceed the friction under normal use, which is the same as the friction type high-strength bolt. When the load is increased again, the relative slip will occur between the connecting plates. The connection relies on the shearing of the screw and the pressure of the hole wall to transmit the force, which is the same as the ordinary bolt, so the difference between the screw and the screw hole is slightly smaller, 1.0~1.5mm. Column anchor 19. Anchor bolts have no grade, only material points: Q235 and Q345. The most anchor bolts on the building structure are the anchor bolts. 20. Column anchors are neither ordinary bolts nor high-strength bolts. Strictly speaking, it is not a bolt. Column anchors are generally M20 or M24. 21. The manufacturing standards for column anchors should be the same as those for ordinary bolts. The length of the column anchor should be related to the friction between it and the concrete, and also the form of the anchor. Expansion bolts and chemical bolts 22. Whether it is an expansion anchor or a chemical anchor, it is not a connection form in the national standard. Avoid using such connections, especially in important connections. All pre-embedded parts should be used. 23. The expansion anchor is mainly pulled by the expansion of the expansion tube and the friction of the crucible. The size of the pull-out force has a great relationship with the construction process, and the human factor is large. It is useless to perform the tensile test. 24. The chemical anchor bolt is formed by punching with a punching machine, and the plug is placed, and then poured into a chemical slurry to form an anchoring action. Common brands such as Fischer and Heineken. 25. Expansion bolts and chemical bolts are actually anchored. In some cases, expansion bolts or chemical anchors are required because they are not pre-buried. But this situation should be avoided in the design. Because the anchors should be pre-buried. For example, column anchors. Because this is the only way to ensure the best bonding and stress. And after the hole punching, it often causes damage to the steel bars and the shackles in the shackles. 26. In the regulations, the components embedded in the concrete are called embedded parts. According to the Ministry of Construction documents, expansion bolts shall not be used for curtain walls. Generally, new construction projects are strictly prohibited, and expansion anchors are strictly forbidden. The above is the basic knowledge of the hex screw, which is more comprehensive.

Screw selection in product assembly design, a more important link is the connection between the components and components. There are pin connection, interference connection, thread connection and so on. The most common way that is commonly used is thread connection. Because most of the company's parts for plastic parts and hardware. How to choose screws correctly has become the key to design thread connection, the following three aspects to explain how to choose and use screws: Type and application of screws 2. Comparison table between screws and materials of plastic components 3. Description of screws 1. 1) Material according to the material of the screw can be divided into: a) carbon steel screw B) stainless steel screw C) copper screw a) carbon steel screw carbon steel screw Silk is a common type of screw, its low price, widely used in the requirements of low and bear torque general alignment, such as the internal structure of the body and other places. Carbon steel screws can also add hard to bear for torque big occasions, such as cooperate with metal (aluminum or iron). Carbon steel screws to improve its performance and enhance its characteristics, prevent rust and meet other special requirements, all can take surface treatment methods such as black, nickel plating, chrome plating, zinc plating, copper plating, etc. Black screw (scientific name hair blue) appearance is black, generally using chemical or electrochemical methods. At present, alkaline chemical oxidation method is used in production to improve its corrosion resistance, because the main component of the outer oxide film is Fe3O4. Therefore, it can only be used in general conditions or oily media. Blackened screws are rarely used in our company's products, mainly considering the impact of appearance, we will use blackened screws. Nickel plated screw appearance is white, magnetic, stable to water and air at room temperature; Soluble in dilute acid; Nickel plated screws are widely used in our products for their appearance, corrosion resistance and production cost, such as common connecting screws including box body. Chrome-plated screws are silvery white in appearance and have strong passivation ability in air to maintain gloss for a long time. Chrome plating has high hardness and excellent wear resistance, but the cost is higher than nickel plating screws. It is used for some appearance requirements or screw hardness requirements

Hex nuts are divided into three types: I, II and thin according to their nominal thickness. Nuts above level 8 are divided into two types, type I and type II. The type II hex nut is relatively thick, and is often used in occasions where assembly and disassembly are often required. I-type nut refers to a common hexagon nut with a nominal height m ≥ 0.8D of the nut. ?? The height of the type II nut is higher than that of the type 1 nut, and its type size should conform to GB / T6175. The purpose of adding a type II nut is twofold: one is to obtain a relatively inexpensive nut without heat treatment by increasing the height of the nut. Because class 8 I-type nuts with D ≤ M16 do not need to be heat treated, in class 8 nuts, type 2 nuts are only used for specifications of D> M16 ~ 39. Obviously, the I-type nut without heat treatment cannot meet the mechanical performance requirements of a 9-level nut. The other purpose of specifying a type II nut is to obtain a tougher grade 12 nut. As the height of the nut increases, the guaranteed stress index can be achieved at a lower quenching and tempering hardness, so the toughness of the nut is increased. Classified by pitch: standard teeth, regular teeth, fine teeth, very fine teeth and anti-tooth. ?? Classified by material: stainless steel hexagonal nut and carbon steel hexagonal nut, copper hexagonal nut, iron hexagonal nut. ?? Classified by thickness: hexagonal thick nuts and hexagonal thin nuts. ?? Classified by use: hot-melt copper nuts, hot-pressed copper nuts, embedded copper nuts and ultrasonic copper nuts Hex nut as a standard part, it should have its own universal specifications ?? For hexagonal nuts, commonly used standards are: GB52, GB6170, GB6172 and DIN934, the main differences between them are: the thickness of GB6170 is thicker than GB52, GB6172 and DIN934, commonly known as thick nuts. The other is the difference between the opposite sides. In the M8 nut series, the opposite sides of DIN934, GB6170, and GB6172 are 13MM, which is 1MM smaller than the opposite side of GB52, which is 14MM, and the M10 nut. GB6170 and GB6172.

In production, flat washers with high parallelism accuracy are often encountered. How to ensure the accuracy of parallelism has always been a difficult problem in production. When grinding a flat washer with a parallelism requirement of 5Pm, after testing, the method of padding 45 steel plate on the flat grinding disk basically solves the problem. The steel plate is placed on the flat grinding disk in order to prevent the workpiece from being deformed by excessive magnetic force, and then the workpiece can be attracted by the magnetic permeability of the steel plate. The processing method after the pad steel plate is as follows:
