Professional Applications & Engineering Value
This split lock washer delivers critical vibration resistance in demanding industrial environments where mechanical fasteners face constant stress and movement. The zinc-plated steel construction provides dual benefits: the base steel offers Rockwell C38 hardness for maintaining spring tension under load, while the zinc coating protects against corrosion in harsh operating conditions. Engineered specifically for 3/4" screw applications, this washer prevents rotational loosening in heavy machinery, construction equipment, and manufacturing assemblies. The split lock design creates continuous spring tension against both the bolt head and seating surface, effectively resisting vibrational forces that compromise joint integrity in industrial applications.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications with 0.766" inner diameter, 1.265" outer diameter, and 0.188" thickness, engineered for optimal performance with 3/4" screws. Manufactured to ASME B18.21.1 standards for dimensional consistency and mechanical properties, this standard lock washer type ensures reliable performance across industrial applications. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and safety requirements for industrial components.
