Professional Applications & Engineering Value
This steel split lock washer delivers critical vibration resistance in industrial environments where mechanical stress and constant motion threaten fastener integrity. The 0.45" internal diameter precisely accommodates 7/16" screws while the split lock design creates continuous spring tension that counters rotational loosening. Engineered to Rockwell C38 hardness, these washers maintain their spring properties through repeated compression cycles, making them ideal for machinery, automotive assemblies, and heavy equipment where vibration-resistant fastening is essential. The standardized dimensions ensure interchangeability across maintenance and production lines, reducing downtime and replacement costs.
Specification Summary & Compliance
This split lock washer features precise dimensional specifications with 0.45" ID, 0.776" OD, and 0.109" thickness, manufactured to ASME B18.21.1 standards for dimensional accuracy and performance reliability. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications. The standard split lock configuration provides consistent performance across inch-system fastening requirements.
