Manufactured from Grade 2 steel with a zinc-plated zinc flake finish, this washer measures 0.778 inches outer diameter and accepts a 1\/2 inch thread size with an inside diameter range of 0.522 to 0.538 inches. The wedge lock design creates a mechanical locking action between mating surfaces, resisting loosening without adhesives or thread-locking compounds. This washer is installed by licensed tradespeople and maintenance professionals in mechanical, HVAC, electrical, and structural fastening applications.\u003c\/p\u003e\n\u003cp\u003eThe MP31516 wedge lock washer is suited for both residential and commercial applications where reliable fastener retention is critical. Typical install scenarios include equipment mounting, panel and bracket assemblies, and vibration-prone mechanical connections. The zinc flake coating provides corrosion resistance for moderate-exposure environments. Sold in packages of 10, with a minimum order quantity of 1 package, this washer is a practical stocking item for field service kits and shop inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWedge lock profile resists fastener loosening under vibration without thread-locking compounds\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for general-purpose fastening strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated zinc flake finish for corrosion resistance in moderate-exposure environments\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch thread size with 0.522 to 0.538 inch ID range for precise fitment\u003c\/li\u003e\n  \u003cli\u003e0.778 inch OD with 0.762 inch minimum OD ensures consistent bearing surface coverage\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 10 for convenient field and shop use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fitment wedge lock washer for 1\/2 inch threaded fastener assemblies in general mechanical, HVAC, electrical, and industrial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of wedge lock washers should be performed by qualified tradespeople familiar with fastener torque procedures appropriate to the application and bolt grade in use. Always de-energize equipment and relieve system pressure before servicing fastened assemblies. Install washers in mating pairs with the cam faces engaged for proper locking action.
