Fender washers feature a larger outer diameter relative to the center hole, spreading load over a broader surface area to reduce fastener pull-through and protect softer or oversized mounting surfaces. The 5\/16 inch inner diameter fits standard 5\/16 inch bolts and screws. The zinc plating provides corrosion resistance suitable for general indoor and light outdoor applications. These washers are a staple fastener component for mechanical, electrical, plumbing, and HVAC service work where secure, distributed clamping is required.\u003c\/p\u003e\u003cp\u003eThis washer is used across residential and light commercial trade work wherever a 5\/16 inch fastener needs increased bearing surface. Common applications include sheet metal panel mounting, equipment anchoring, conduit and cable management hardware, and general structural fastening. The 100-pack quantity suits service vans and shop stock for ongoing maintenance and installation work across multiple trade disciplines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eZinc plated finish provides corrosion resistance for general service environments\u003c\/li\u003e\n\u003cli\u003eFender washer design distributes load over a larger surface area to reduce fastener pull-through\u003c\/li\u003e\n\u003cli\u003e5\/16 inch inner diameter fits standard 5\/16 inch bolts and fasteners\u003c\/li\u003e\n\u003cli\u003e1-1\/2 inch outer diameter provides broad bearing surface\u003c\/li\u003e\n\u003cli\u003eSteel construction for reliable mechanical strength\u003c\/li\u003e\n\u003cli\u003e100-pack quantity supports stock replenishment and multi-job use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 5\/16 inch bolts, screws, and threaded fasteners across HVAC, plumbing, electrical, and general mechanical assembly applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires no specialized tools beyond the wrench or driver used for the mating fastener. Ensure the washer is seated flat against the work surface before torquing the fastener. For outdoor or high-moisture environments, verify that the zinc plating is sufficient for the corrosion exposure level of the application. Always follow applicable mechanical and structural codes for fastener assembly requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc Plated Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWasher Type\u003c\/strong\u003e: Fender Washer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 31 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HILLMAN FASTENERS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 290027\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HILLMAN","offers":[{"title":"Default Title","offer_id":51558278136114,"sku":"290027","price":214.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39202b3a894cf49939021e67f818a868_10894377-64be-46ab-957e-8cdbe7560ab0.jpg?v=1786408266","url":"https:\/\/voomisupply.com\/products\/hillman-fasteners-290027-fender-washer-5-16x1-1-2-in-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
