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. 

GB10433 Welding Shear Stud refer to the installation of steel pins or grommets, that extend out of the top flange of a steel support beam. Normally the GB10433 Welding Shear Stud 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 GB10433 Welding Shear Stud directly to the top of the steel beam.

ASTM A325 Heavy Hex Structural Bolt with its unique design, our butterfly bolts have a spring-loaded toggle that expands behind the wall once installed. This ensures a secure anchor point that can support a wide range of weights, ensuring whatever you're attaching stays in place. ASTM A325 Heavy Hex Structural Bolt can be used with a wide variety of materials, such as drywall, plaster, and even concrete. We offer our butterfly bolts in a variety of sizes to best fit your needs.

En14399-4 Grade10 Black Hex Nut with Hv also called structural nuts, are both thicker and wider than a standard (finished) hex nut and compatible with high strength and large diameter bolts. En14399-4 Grade10 Black Hex Nut with Hv in sizes smaller than 7/16" are double chamfered. En14399-4 Grade10 Black Hex Nut with Hv larger than 7/16" are either double chamfered or chamfered on top with a washer faced bearing surface.

DIN970 Metric Hexagon Nut play the role of a component of all manufacturing machinery.DIN970 Metric Hexagon Nut can fastener other components. DIN970 Metric Hexagon 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 DIN970 Metric Hexagon Nut. DIN970 Metric Hexagon Nut is very common.
