Professional Applications & Engineering Value

This stainless steel spring lock washer delivers critical vibration-resistant performance in demanding industrial applications where fastener loosening poses significant safety and operational risks. The conical shape with external teeth creates multiple biting points that dig into both the bearing surface and fastener, creating mechanical interference that counters rotational forces. Engineered specifically for 1.563"-18 screw sizes, this external tooth lock washer maintains clamping force in high-vibration environments such as heavy machinery, automotive assemblies, and industrial equipment. The chamfered bearing nut face style ensures smooth installation while preventing surface damage, making it ideal for precision assemblies requiring repeated maintenance cycles. Manufactured from corrosion-resistant stainless steel, this component provides long-term reliability in challenging operating conditions where environmental factors would compromise ordinary fasteners.

Specification Summary & Compliance

This spring lock washer features precise dimensional specifications including 1.583" ID, 2.469" OD, 0.063" thickness, and 0.232" overall height with external tooth configuration. The washer is engineered to ANSI/ABMA 8.2 standards for dimensional accuracy and performance requirements, ensuring compatibility with 1.563"-18 screw sizes and chamfered bearing nut applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations confirms suitability for global industrial markets requiring restricted substance control.
