Professional Applications & Engineering Value
This 316 stainless steel split lock washer delivers critical vibration-resistant fastening solutions for demanding industrial applications where equipment reliability is paramount. The split lock washer design creates continuous spring tension against both the bearing surface and fastener, effectively preventing loosening caused by mechanical vibrations, thermal cycling, and dynamic loads. Engineered with marine-grade 316 stainless steel, this component offers superior resistance to chlorides, chemicals, and corrosive environments commonly encountered in marine, chemical processing, and offshore applications. The Rockwell C35 hardness rating ensures optimal spring performance without compromising ductility, making it ideal for heavy machinery, structural assemblies, and precision equipment where vibration-resistant washers are essential for operational safety and maintenance reduction.
Specification Summary & Compliance
This standard split lock washer features precise dimensional specifications with 1.28" inner diameter and 2.036" outer diameter, manufactured to ASME B18.21.1 standards for consistent performance and interchangeability. The component maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability. Designed specifically for use with 1 1/4" screws, this inch-system washer delivers reliable fastening performance across mechanical assemblies requiring vibration-resistant solutions.
