It features an inside diameter of 0.398 inches and an outside diameter of 0.765 inches, with a thickness of 0.034 inches. Manufactured to Grade 2 material standards and conforming to DIN 6797 and DIN 6798 specifications, this washer provides reliable anti-loosening performance by biting into the mating surface as the fastener is tightened. This box contains 100 washers and is suited for mechanical assembly, structural fastening, and general hardware applications across trade industries.\u003c\/p\u003e\n\u003cp\u003eExternal tooth lock washers like this one are commonly used in electrical, HVAC, plumbing, and general mechanical installations where vibration or movement could cause fasteners to back out over time. The external tooth design distributes clamping load around the perimeter of the fastener head, making it effective on thin sheet metal, panels, and mounting brackets. This product ships in a box quantity of 100, making it practical for service vans and shop stock where consistent fastener hardware is needed on repeat jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal tooth design bites into mating surfaces to resist fastener loosening under vibration\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for general indoor and light-duty applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets DIN 6797 and DIN 6798 standards\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.398 inches fits standard 3\/8 inch fasteners\u003c\/li\u003e\n  \u003cli\u003eThickness of 0.034 inches for consistent clamping and minimal stack height\u003c\/li\u003e\n  \u003cli\u003eBox of 100 units supports bulk service and stocking needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/8 inch screws and bolts in standard mechanical and structural fastening applications.
