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.

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

DIN6923 Hex Flange Nuts 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 Hex Flange Nuts 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.

ISO4775 heavy Hexagon Nut are the most commonly used nuts in the fastener industry.ISO4775 heavy Hexagon Nut are relatively strong and durable fasteners that can withstand some special industrial conditions. ISO4775 heavy Hexagon Nut hardness, thickness and tensile strength enable it to withstand some extreme industrial environments.

DIN557 Carbon Steel Square Nuts are Made with top-quality materials, these nuts are known for their durability, strength, and corrosion resistance. DIN557 Carbon Steel Square Nuts are designed to last. The high-quality steel construction provides excellent tensile strength, meaning they can handle high load capacities without deforming or breaking. Galvanized Carbon steel is also resistant to corrosion, so DIN557 Carbon Steel Square Nuts stand up well even in wet and humid environments.

Shear Connector Welding Screw refer to the installation of steel pins or grommets, that extend out of the top flange of a steel support beam. Normally the Shear Connector Welding Screw are welded, with a spot welder, after the metal deck is installed over the supporting structural steel. The spot welder will burn through the metal deck and attach the Shear Connector Welding Screw directly to the top of the steel beam.
