Value Collection MPA98002 Wedge Lock Washer M12 10 Pack

Product Description

The VALUE COLLECTION MPA98002 is a Grade 2 wedge lock washer designed to maintain clamp load in bolted assemblies subject to vibration, dynamic loading, and thermal cycling. The washer measures 0.7677 inches outside diameter with an inside diameter ranging from 0.5039 to 0.5197 inches, sized for M12 thread fasteners. A zinc flake finish provides corrosion resistance in typical indoor and light outdoor service environments. This part is sold in a package of 10. Electricians, mechanical contractors, HVAC installers, and general trade professionals use wedge lock washers wherever fastener loosening under vibration is a concern.

This washer is suited for use in mechanical, electrical, and HVAC panel assemblies, equipment mounting applications, and structural fastening where M12 hardware is specified. The wedge lock design uses opposing serrated faces that bite into the mating surfaces and fastener, resisting rotation under load. Typical applications include securing equipment to frames, mounting electrical enclosures, and any bolted joint where a standard flat or split washer does not provide adequate retention.
