Internal tooth lock washers grip the mating surface through hardened serrated teeth that bite into both the fastener head and the substrate, resisting loosening from vibration and torque. The zinc plating provides a basic level of corrosion resistance suitable for general indoor and light-duty applications. With a thickness of 0.035 inches and a minimum inside diameter of 0.256 inches, this washer is dimensionally consistent for use in standard assembly and maintenance work. Sold in a package of 100 pieces, it suits technicians and tradespeople who need a reliable supply on hand for recurring fastener tasks.\u003c\/p\u003e\n\u003cp\u003eThis washer is appropriate for light-gauge assemblies where screw retention is required in vibration-prone environments. Typical applications include panel mounting, equipment enclosures, junction boxes, and general mechanical assembly across HVAC, electrical, and plumbing trade work. The internal tooth design keeps the washer centered on the fastener during installation, which makes it a practical choice in tight clearances where an external tooth washer would not fit. The Grade 2 steel construction meets the requirements of general-purpose fastener applications that do not call for high-strength or military-specification hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal tooth design centers washer on fastener and grips mating surfaces to resist loosening\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for general-purpose mechanical assembly\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance for indoor and light-duty use\u003c\/li\u003e\n  \u003cli\u003eThickness of 0.035 inches with inside diameter range of 0.256 to 0.267 inches for consistent fit on 1\/4 inch fasteners\u003c\/li\u003e\n  \u003cli\u003eOutside diameter range of 0.68 to 0.695 inches\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 100 for shop stock and service van inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard internal tooth lock washer for use with 1\/4 inch screws and bolts in general mechanical, electrical, and HVAC assembly applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with the teeth facing the fastener head or the workpiece surface to achieve proper gripping action. Electricians, HVAC technicians, and plumbers routinely install lock washers as part of panel, bracket, and equipment fastening under NEC and IFGC guidelines. Ensure the mating surfaces are clean and free of debris before assembly. Do not reuse a compressed lock washer, as the teeth lose gripping effectiveness once fully flattened.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Type\u003c\/strong\u003e: Internal Tooth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.035 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Inside Diameter\u003c\/strong\u003e: 0.256 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Inside Diameter\u003c\/strong\u003e: 0.267 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Outside Diameter\u003c\/strong\u003e: 0.68 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Outside Diameter\u003c\/strong\u003e: 0.695 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilitary Specification\u003c\/strong\u003e: Does Not Meet Military Specifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161801\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: -31369-1\/4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697106387250,"sku":"-31369-1\/4","price":22.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c98ca5503082cee4dcf438be391bf458.jpg?v=1788349444","url":"https:\/\/voomisupply.com\/products\/value-collection-31369-1-4-internal-tooth-lock-washer-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
