Professional Applications & Engineering Value
This spring lock washer delivers critical vibration resistance in demanding mechanical assemblies where dynamic loads and operational stresses threaten fastener integrity. The conical shape and external tooth location work synergistically to create continuous spring tension that compensates for thermal expansion, material relaxation, and vibrational forces. Manufactured from high-grade steel with precise chamfered bearing nut face style, this washer prevents galling and distributes clamping forces evenly across contact surfaces. Ideal for heavy machinery, automotive systems, and industrial equipment requiring reliable lock washers that maintain preload in high-vibration environments while meeting strict ANSI/ABMA 8.2 specifications.
Specification Summary & Compliance
This spring lock washer features precise dimensional specifications including 1.333" inner diameter, 2.234" outer diameter, and 0.217" overall height with external tooth configuration. Manufactured to ANSI/ABMA 8.2 standards for consistent performance in mechanical applications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. Designed specifically for use with 1.312"-18 screw sizes and chamfered bearing nuts, providing reliable fastening solutions for professional engineering applications.
