Professional Applications & Engineering Value
This 5/16" split lock washer delivers critical vibration resistance in demanding industrial environments where mechanical fasteners face constant dynamic stresses. The zinc-plated steel construction provides essential corrosion protection while maintaining the Rockwell C38 hardness necessary for sustained spring tension. Engineered to ASME B18.21.1 standards, these washers solve common loosening issues in automotive assemblies, heavy machinery, and electrical enclosures where thermal cycling and vibration compromise fastener integrity. The split lock design creates continuous outward pressure that counters rotational forces, making them ideal for industrial applications requiring reliable, maintenance-free fastening solutions that withstand harsh operating conditions.
Specification Summary & Compliance
This split lock washer features precise dimensions (0.322" ID, 0.583" OD, 0.078" thickness) manufactured to ASME B18.21.1 specifications for inch-system fasteners. The product maintains dimensional accuracy for 5/16" screw size applications and demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations regarding restricted substances. The standard split lock washer type ensures consistent performance across industrial and automotive applications requiring reliable vibration-resistant fastening solutions.
