  • ASME B18.21.1 Spring Washer

    ASME B18.21.1 Spring Washer

    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.

  • DIN6923 Hex Flange Nuts

    DIN6923 Hex Flange Nuts

    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.
  • ASTM A325 Heavy Hex Bolt

    ASTM A325 Heavy Hex Bolt

    ASTM A325 Heavy Hex Bolt are designed for steel-to-steel structural connections. Consequently, they are typically very short. The A325 and A490 specifications are not intended for general applications, including anchor bolts. In these applications, substitutions of A449 for A325 and A354 grade BD for A490 should be considered.
  • DIN985 Nylon Hex Lock Nut

    DIN985 Nylon Hex Lock Nut

    DIN985 Nylon Hex Lock Nut designed to withstand heavy loads and extreme temperatures, ensuring long-lasting performance and reliability. Hexagonal shape making it easy to grip and tighten securely with a wrench or pliers. DIN985 Nylon Hex Lock Nut shape provides additional support and stability, making it less likely to loosen or come apart under heavy strain. The hexagonal shape of the nut also provides a secure grip and helps to prevent accidental loosening.
