Professional Applications & Engineering Value

This black-oxide steel split lock washer delivers exceptional engineering value in applications where vibration resistance is critical. The split lock design creates constant spring tension that compensates for material relaxation and thermal cycling, preventing fastener loosening in machinery, automotive assemblies, and heavy equipment. The black-oxide surface treatment provides corrosion resistance without significantly altering dimensions, making it ideal for precision assemblies requiring 7/16" screw sizes. Manufactured to ASME B18.21.1 standards, these washers ensure consistent performance in industrial environments where reliability cannot be compromised. The combination of Rockwell C38 hardness and precise dimensional control makes them suitable for both original equipment manufacturing and maintenance applications across multiple industries.
