Professional Applications & Engineering Value
This spring lock washer addresses critical vibration-induced fastener failure in demanding industrial environments. The hardened steel construction with Rockwell C40 hardness maintains structural integrity under repeated stress cycles, while the dual-sided serration pattern creates positive mechanical locking action on both contact surfaces. This design proves particularly valuable in automotive assemblies, heavy machinery, and electrical enclosures where constant motion or operational vibrations threaten joint integrity. The washer's inch and metric compatibility (#6 and M3.5) provides flexibility for global equipment manufacturers, eliminating the need for multiple washer types in multinational production environments.
Specification Summary & Compliance
Precision-engineered dimensions include 0.146" internal diameter, 0.236" outer diameter, and 0.035" overall height with 0.018" material thickness. The spring lock washer features standardized serration geometry optimized for maximum locking performance. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring unrestricted use in international markets. The hardened steel material with Rockwell C40 hardness provides consistent mechanical properties batch-to-batch for reliable performance in critical fastening applications.
