Professional Applications & Engineering Value
These heavy-duty split lock washers solve critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and construction equipment. The zinc-plated steel material provides dual protection against corrosion while maintaining the necessary spring tension to keep fasteners securely locked. The standard split lock washer design creates continuous upward force that counters rotational movement, making them ideal for applications where thermal cycling, mechanical stress, or constant vibration threaten joint integrity. Engineered to ASME B18.21.1 specifications, these washers deliver predictable performance in demanding environments from manufacturing plants to outdoor infrastructure projects.
Specification Summary & Compliance
This 5/16" split lock washer features precise dimensional tolerances with 0.322" inner diameter, 0.457" outer diameter, and 0.093" thickness. Manufactured to ASME B18.21.1 standards for dimensional accuracy and performance requirements. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications while meeting international quality and safety standards.
