Manufactured from Grade 2 steel with a zinc flake finish over zinc plating, it provides corrosion resistance suitable for general industrial and mechanical applications. The washer fits a 5\/16-inch or M8 thread with an outside diameter of 0.534 inches and an inside diameter ranging from 0.336 to 0.344 inches. Its wedge-profile mating faces create a locking action that resists loosening under load. Sold in packs of 25, this washer is installed by maintenance technicians, millwrights, and mechanical contractors across a wide range of bolted joint applications.\u003c\/p\u003e\n\u003cp\u003eThis washer is suited for use in general mechanical assemblies, HVAC equipment mounting, electrical enclosure hardware, and light structural connections where vibration-induced fastener loosening is a concern. The inch-system dimensions and 5\/16-inch thread compatibility make it a straightforward fit in standard North American fastener assemblies. The zinc-plated zinc flake finish offers moderate environmental protection for indoor and sheltered outdoor installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWedge-profile locking geometry resists fastener loosening under vibration and dynamic load\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction provides reliable mechanical strength for general-duty applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated with zinc flake finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eFits 5\/16-inch (M8) threaded fasteners; OD 0.534 inches, ID 0.336 to 0.344 inches\u003c\/li\u003e\n  \u003cli\u003eCompliant with ISO 14001 and ISO 9001 manufacturing standards\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 25 with a minimum order quantity of 1 pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard wedge lock washer for 5\/16-inch (M8) bolted assemblies using inch-system fasteners in general industrial, mechanical, and HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eWedge lock washers are installed in pairs with the serrated faces mating against each other, placed between the fastener bearing surface and the joint material.
