Professional Applications & Engineering Value
These heavy-duty split lock washers are engineered to solve critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and construction equipment. The zinc-plated steel material provides essential corrosion protection while maintaining the Rockwell C38 hardness necessary for sustained locking force. The split design creates continuous spring tension that actively counters rotational forces, making these ASME B18.21.1 compliant washers ideal for high-vibration environments where fastener security is paramount. Their precise 5/8" sizing ensures reliable performance in mechanical fastening systems requiring consistent, long-term vibration resistance without compromising assembly integrity.
Specification Summary & Compliance
This standard split lock washer features precise dimensions: 0.641" inner diameter, 0.917" outer diameter, and 0.203" thickness, specifically engineered for 5/8" screw applications. Manufactured to ASME B18.21.1 specifications with Rockwell C38 hardness certification, ensuring consistent mechanical properties and reliable locking performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest industry standards for hazardous substance restrictions and chemical safety protocols.
