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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWedge lock geometry resists fastener loosening under vibration and dynamic loads\u003c\/li\u003e\n\u003cli\u003eM12 thread size with inside diameter from 0.5039 to 0.5197 inches\u003c\/li\u003e\n\u003cli\u003eOutside diameter 0.7677 inches, minimum OD 0.7598 inches\u003c\/li\u003e\n\u003cli\u003eGrade 2 material construction\u003c\/li\u003e\n\u003cli\u003eZinc flake finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 10 per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a wedge lock washer for use with M12 fasteners in bolted assemblies requiring vibration-resistant clamping.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by placing the washer pair between the fastener bearing surface and the mating workpiece, with the serrated faces oriented toward each other per manufacturer intent.
