It is designed to resist loosening caused by vibration by biting into the bearing surface of a fastener and the mating material. The washer features an inside diameter of 0.231 inches, an outside diameter of 0.475 inches, and a thickness of 0.025 inches. It is suitable for use in corrosion-prone environments where stainless steel is required. This item is sold in a package of 100 washers, making it practical for production assembly, maintenance shops, and service vehicles.\u003c\/p\u003e\u003cp\u003eExternal tooth lock washers in this size are commonly used with No. 12 machine screws in light mechanical assemblies, electrical enclosures, HVAC equipment panels, and plumbing fixture hardware. The external tooth design provides maximum locking force and is best suited for applications where the full washer face is visible and accessible. Grade 410 stainless steel offers a good balance of corrosion resistance and hardness, making these washers a reliable choice in moderate to mildly corrosive environments such as outdoor equipment housings or wet mechanical spaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExternal tooth design bites into bearing surface to resist vibration-induced loosening\u003c\/li\u003e\n\u003cli\u003eGrade 410 stainless steel construction for corrosion resistance and hardness\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.231 inches fits No. 12 screw size\u003c\/li\u003e\n\u003cli\u003eOutside diameter of 0.475 inches and thickness of 0.025 inches\u003c\/li\u003e\n\u003cli\u003eSold in a 100-piece package for high-volume service and assembly work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with No. 12 machine screws and fasteners requiring an external tooth lock washer with a 0.231-inch inside diameter.
