ASME B18.21.1 Spring Washer are widely used in load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and convenient installation, and are suitable for the parts with frequent assembly and disassembly. ASME B18.21.1 Spring Washer in the screw industry, often called ASME B18.21.1 Spring Washer. The benefit of spring lock washers lies in the trapezoidal shape of the washer. When compressed to loads near the proof strength of the bolt, it will twist and flatten. This reduces the spring rate of the bolted joint which allows it to maintain more force under the same vibration levels. This prevents loosening.

DIN127A Lock Single Coil Spring Washer are commonly used metric lock washers, As you tighten a bolt, these DIN127A Lock Single Coil Spring Washer flatten to add tension to the threaded joint and prevent loosening from small amounts of vibration. DIN127A Lock Single Coil Spring Washer meet a DIN or ASME standard for split lock washer dimensions. Standard DIN127A Lock Single Coil Spring Washer have a left-hand helix, which means you can only use them with bolts that have right-hand threads to prevent clockwise rotation from vibration. 

ISO13918 - Aws - D1.1/D1.1m - Welding Nail are designed to tie the concrete slab with the steel beams and steel deck. This weld studs shear connectors can resist shear forces and increase shear loading capacity in steel buildings. ISO13918 - Aws - D1.1/D1.1m - Welding Nail Mainly applied for through steel deck stud welding in composite construction project. All Shear Studs are supplied with ceramic ferrules (ceramic ring). The Ceramic ferrules are made of cordierite and able to withstand heat shock as well as high temperatures without melting or breaking

ASTM F436 Steel Structure Metal Flat Round Washer is stamped piece from, The shape is round with a hole in the middle. ASTM F436 Steel Structure Metal Flat Round Washer have a smooth bearing surface which is used under the head of a bolt, ASTM F436 Steel Structure Metal Flat Round Washer are used to reduce friction, The force is unoform, It is not easy to slip and lock in the process of rotation, and it is anti loose design, prevent leakage, isolate, prevent loosening, or distribute pressure.

ISO4033 Hex Head Nut play the role of a component of all manufacturing machinery.ISO4033 Hex Head Nut can fastener other components. ISO4033 Hex Head Nut have kinds of nut. We have common national standard, German standard, the British standard, American Standard, the subject of the nut. There are many kinds of ISO4033 Hex Head Nut. ISO4033 Hex Head Nut is very common.

DIN6923 Flange Head Nut provide a secure and tight fit, while also preventing the nut from loosening due to vibration. This is especially important in industries where machinery and other heavy equipment are used, as any loosening of fittings can cause dangerous and costly consequences. The flange of DIN6923 Flange Head Nut acts as a washer, providing additional support while preventing the nut from embedding itself into the surface of the material being fastened. This greatly reduces the risk of damage to the structure, as well as providing a more aesthetically pleasing finish.
