Manufactured from Grade 2 spring steel with a zinc-plated finish, this washer provides reliable vibration resistance and secure fastening in mechanical and electrical assemblies. The internal tooth design bites into both the fastener bearing surface and the mating material, creating a locking action that resists loosening under dynamic loads. With a 0.267 inch inside diameter and 0.536 inch outside diameter, it fits standard 1\/4 inch fastener applications. This package contains 100 washers, sold as a single box.\u003c\/p\u003e\n\u003cp\u003eInternal tooth lock washers of this type are used across a wide range of trade applications including electrical panel assemblies, HVAC equipment mounting, plumbing fixture hardware, and general mechanical fastening. The zinc plating provides corrosion resistance suitable for indoor and moderately controlled environments. Licensed electricians, HVAC technicians, plumbers, and maintenance professionals commonly use these washers when securing equipment to metal enclosures, mounting brackets, and sheet metal structures where vibration-induced loosening is a concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal tooth design provides 360-degree grip on fastener and mating surface to resist loosening from vibration\u003c\/li\u003e\n  \u003cli\u003eGrade 2 spring steel construction delivers consistent locking force and hardness\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish adds corrosion resistance for indoor and controlled-environment installations\u003c\/li\u003e\n  \u003cli\u003e0.267 inch inside diameter sized for standard 1\/4 inch screws and bolts\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty designation for demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003eSold in a 100-piece box for high-volume service and repair work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock internal tooth lock washer for 1\/4 inch screw fastener applications in electrical, HVAC, plumbing, and general mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with the teeth facing the fastener head or nut bearing surface, not against the workpiece, to maximize locking effectiveness. Power down all electrical equipment and relieve any system pressure before disassembling fastened connections. Use appropriate torque tools to avoid over-tightening, which can flatten the teeth and reduce locking performance. These washers are intended for indoor or protected environments; consult project specifications if corrosion resistance requirements are more demanding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: Spring Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.267 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.536 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.039 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeatures\u003c\/strong\u003e: Heavy Duty\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: 1 pound\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: SIWIS0250HDUSA-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690911858994,"sku":"SIWIS0250HDUSA-100BX","price":2303.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/715aaf9d0bd0bec7edacc491155f6dbc.jpg?v=1788277487","url":"https:\/\/voomisupply.com\/products\/value-collection-siwis0250hdusa-100bx-lock-washer-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
