Fender washers feature an oversized outer diameter relative to the bolt hole, distributing clamping load across a wider surface area. This reduces the risk of pull-through on thinner or softer materials. The zinc plating provides basic corrosion resistance suitable for general indoor and light-duty outdoor applications. These washers are sold as a single jar containing 100 pieces, making them practical for repetitive fastener work on job sites or in shop inventory.\u003c\/p\u003e\n\u003cp\u003eThese fender washers are used across a wide range of trade applications including HVAC equipment mounting, electrical panel and junction box work, plumbing support brackets, and general mechanical assembly. The 3\/8 inch bolt clearance is one of the most common fastener sizes encountered in residential and light commercial construction and service work. The oversized 1-1\/4 inch outer diameter makes them well suited for installations where the substrate requires broader load distribution, such as sheet metal, thin gauge brackets, or wood backing boards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch inner diameter fits standard 3\/8 inch bolts and threaded rod\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch outer diameter provides wide load distribution to minimize pull-through\u003c\/li\u003e\n  \u003cli\u003eZinc plating offers corrosion resistance for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eJar of 100 pieces keeps fasteners organized and countable on the job\u003c\/li\u003e\n  \u003cli\u003eSuitable for use across HVAC, plumbing, electrical, and general mechanical applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/8 inch bolts, screws, and threaded rod in standard fastener assemblies across residential and light commercial trade applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFender washers are installed by any trade working with 3\/8 inch fasteners. Place the washer on the bolt or screw before driving into the substrate to ensure full contact between the washer face and the work surface. Do not over-torque fasteners, as excessive clamping force can deform the washer and reduce load distribution effectiveness. Follow applicable mechanical or building code requirements for fastener spacing and load ratings on structural connections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1-1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Jar\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662352112598\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: STEWART FASTENER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J3720WFZ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STEWART FASTENER","offers":[{"title":"Default Title","offer_id":51383452795186,"sku":"J3720WFZ","price":31.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312672002.jpg?v=1782597098","url":"https:\/\/voomisupply.com\/products\/stewart-fastener-j3720wfz-3-8x1-1-4-zinc-fender-washers-100pk","provider":"Voomi Supply","version":"1.0","type":"link"}
