1.Hexagonal bolts are widely used both indoors and outdoors. Outdoor applications are mostly for building installations, bridges and roads, and power facilities; indoor applications are mostly for mechanical equipment, medical equipment, and electronic equipment.
2.When hexagonal bolts are used in electronic equipment, medical equipment, and other places, stainless steel hexagonal bolts are generally selected because the surface color of stainless steel is more beautiful and the corrosion resistance is better, which can keep the machine beautiful for a long time. If it is a mechanical equipment with large vibration, it is recommended to choose high-strength hexagonal bolts.

It is safe, stable, and not easily loosened.
Cross recessed pan head wood screws are widely used in the following fields because of their unique structure: ● Furniture manufacturing: used to connect various parts of furniture to ensure its stability and strength. ● Automobile manufacturing: used for the tight connection inside the automobile to improve the safety and reliability of the automobile. ● Woodworking: used for the assembly and fixing of wood products to improve the durability of wood products. ● Mechanical manufacturing: used for the assembly and fixing of various mechanical equipment to ensure the normal operation of the equipment.
GB 853 square diagonal washers are mainly used for connecting channel steel, especially in situations where fastening is required along the groove direction of the channel steel. The GB 853 standard provides detailed specifications for the size range, tolerance requirements, material selection, and performance indicators of square diagonal washers for channel steel, ensuring that the washers can effectively disperse loads and prevent local stress concentration at the connection points.
1. Adjust the tension of the steel wire rope: By using a lead screw for expansion and contraction, the tension of the steel wire rope can be adjusted, which is suitable for situations that require frequent adjustment 2. Fixation and binding: It can be used to bind and fasten steel wire ropes, especially suitable for power lines, especially as a positioning device for high-voltage tower tie rods 3. Provide support: It can be used to fix the bottom of the flower basket as a support point to ensure its stability 4. Multiple application scenarios: The application areas cover multiple industries such as electricity, logistics, and agriculture, such as cargo bundling, sling connections, and steel structure cable rod connectors in logistics
1. Fixation and connection: The main function of U-bolts is to fix and connect various equipment or objects. Due to its unique U-shaped design, it can firmly secure tubular or sheet-like objects, ensuring that they do not loosen or move during use. For example, in the automotive industry, U-bolts are commonly used to connect and secure steel plate springs to maintain the stability of the car chassis 2. Able to withstand multiple forces: U-bolts can withstand tensile and shear forces, and have strong vibration resistance. This means that it can maintain stability under different stress conditions, making it suitable for applications that require high stability. For example, in bridge, tunnel, and railway construction, U-bolts are widely used to ensure the stability and safety of the structure In summary, U-bolts play an important role in fixing, connecting, withstanding various forces, space utilization, and wide application fields. Its design and material selection make it one of the indispensable fasteners in many industries.
1. The cap nut and stainless steel hexagonal slotted nut are matched with an open pin and threaded bolt with holes to withstand vibration and alternating loads, which can prevent the nut from loosening and coming out. 2. Cap shaped nuts with inserts, which rely on tightening the nut to tap the internal thread, can provide anti loosening effect and have good elasticity. The purpose of the 3-cap nut is the same as that of the hex nut. Its characteristic is that when assembling and disassembling, a wrench is used to clamp the main nut, which is not easy to slip. However, only an adjustable wrench, a fixed wrench, a dual-purpose wrench (for the opening part), or a specially designed square hole socket wrench can be used for assembly and disassembly. Mostly used on rough and simple components. 4. Cap nuts are suitable for high-strength fasteners, mechanical fasteners, furniture fasteners, vehicle fasteners, machining special-shaped parts, cold heading special-shaped fasteners, double headed foot U-wires, and building decoration fasteners
DIN582 lifting ring nuts are mainly used to connect chains and steel wire ropes, and can also be used for lightweight lifting. The hanging ring nut refers to a component that is screwed together with a bolt or screw to provide a fastening effect, and is a necessary component for all production and manufacturing machinery.
1.A washer is a seal that fills the gap between two mating surfaces, allowing the two workpieces to be connected together without leakage even when compressed. 2.A washer can fill some irregularities on the surface, allowing for some imperfections in the mating surfaces of the workpieces. washer are generally made by cutting and splitting thin sheets. 3.Generally speaking, the ideal washer material is one that allows a certain degree of deformation so that it can deform and fill the corresponding space (including some slight irregularities) during assembly. Some washer require the addition of sealants directly to the surface in order for the gasket to work properly.
DIN937 hexagonal slotted thin nuts are mainly used for machines and equipment that require frequent disassembly, especially in situations where space is limited. This type of nut has six parallel short grooves at its bottom, which can be rotated using a wrench or pliers, making it easy to disassemble and install
DIN127 spring washers are mainly used in bolt connections, especially in bolt connections with a strength grade of 5.8 or below. Its main purpose is to prevent bolt loosening by increasing the axial rebound force to compensate for the loss of preload force caused by compression, thereby preventing the loosening of threaded connections.
Hexagonal locking thin nuts are also widely used in the production and manufacturing processes of various mechanical equipment, instruments, household appliances, etc.
1. Preventing loosening: The main function of spring washers is to prevent loosening of fasteners (such as nuts and bolts) through their elasticity and oblique friction. When the nut is tightened, the spring washer is compressed, generating a reverse force that increases the friction between the nut and bolt, effectively preventing loosening 2. Reduce friction: Spring washers can also reduce friction between nuts and bolts, making fasteners less likely to loosen when subjected to vibration. This characteristic is particularly important for mechanical equipment that is frequently subjected to vibration or impact 3. Expand contact area: Although flat washers are mainly used to expand contact area and disperse pressure, spring washers can also play a similar role to some extent. Especially when the strength of the connected parts is low, using flat pads or flange bolts can increase the contact area, while spring washers can further prevent loosening 4. Special applications: In some special cases, the use of spring washers depends on specific engineering requirements.
1.Installation steps: ① Punch a hole ② Hammer the casing into the air ③ Screw the screw into the wall anchor ④ Installation is complete 2.Scope of application: Suitable for home decoration, industrial building materials, medical equipment, etc. 3.Product features: small and light, easy to carry, easy to take, strong and durable
Hexagonal embedded locking nut is a type of fastener that can lock threads. It is widely used in fields such as mechanical manufacturing, automotive manufacturing, and electronic equipment. In high-speed mechanical equipment, locking nuts can effectively prevent thread loosening and ensure the safe and stable operation of the equipment.
