Built to an M20 thread size with a maximum outside diameter of 1.2087 inches and a maximum inside diameter of 0.8504 inches, this washer uses a cam-action wedge profile to resist loosening under load. The zinc flake finish over a Grade 2 material base provides corrosion resistance suitable for general industrial and mechanical applications. Each package contains 10 washers, sold in a minimum order quantity of 1 package.\u003c\/p\u003e\u003cp\u003eWedge lock washers in this size range are used across a wide variety of industrial assembly, equipment maintenance, and structural fastening applications. They are commonly installed wherever standard flat or split washers are insufficient to prevent fastener backout due to vibration or repeated stress cycles. Typical end users include millwrights, maintenance technicians, mechanical contractors, and industrial assemblers working on machinery, structural steel, HVAC equipment frames, and heavy fabrications requiring reliable bolt retention.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCam-action wedge profile resists fastener loosening under vibration and dynamic loading\u003c\/li\u003e\n\u003cli\u003eM20 thread size with 1.2087 inch maximum OD and 0.8504 inch maximum ID\u003c\/li\u003e\n\u003cli\u003eMinimum OD of 1.2008 inches and minimum ID of 0.8346 inches for dimensional consistency\u003c\/li\u003e\n\u003cli\u003eZinc flake finish provides corrosion protection for general service environments\u003c\/li\u003e\n\u003cli\u003eGrade 2 material construction suitable for standard industrial fastening applications\u003c\/li\u003e\n\u003cli\u003ePackaged 10 pieces per unit for efficient stocking and use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with M20 fasteners in bolted assemblies requiring vibration-resistant locking.
