Professional Applications & Engineering Value

This M5 metric spring lock washer delivers critical engineering solutions where vibration-induced fastener failure is a primary concern. The black-oxide stainless steel construction provides dual protection against corrosion and wear, making it indispensable for automotive assemblies, machinery manufacturing, and outdoor equipment exposed to moisture and chemicals. The spring lock mechanism creates continuous tension that compensates for thermal expansion and mechanical settling, eliminating the need for frequent retightening in vibration-resistant applications. With its 0.5mm thickness and precise dimensional tolerances, this washer maintains consistent performance in confined spaces while the Rockwell C38 hardness ensures long-term reliability in high-stress industrial environments.

Specification Summary & Compliance

Manufactured to precise metric dimensions (5.2mm ID, 10mm OD, 0.5mm thickness) with standard M5 screw compatibility. The black-oxide stainless steel construction meets industry standards for corrosion resistance and mechanical performance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and global market acceptance. The Rockwell C38 hardness rating confirms consistent material properties and reliable performance in demanding applications.
