With a 1\/8 inch rivet diameter fit, a 0.129 inch inside diameter, a 0.375 inch outside diameter, and a thickness of 0.06 inches, this washer provides a stable bearing surface beneath the rivet head or tail. It is used by sheet metal workers, HVAC installers, electricians, and general contractors wherever blind rivets are driven into soft, thin, or fragile substrates that require load spreading to prevent pull-through or surface damage.\u003c\/p\u003e\n\u003cp\u003eThis washer is suited for residential and light commercial fastening applications involving aluminum, sheet metal, plastic panels, or other thin materials. It pairs with standard 1\/8 inch blind pop rivets and is installed on the blind side of the joint before setting the rivet. The plain aluminum finish offers adequate corrosion resistance for indoor and sheltered outdoor environments. Each package contains 250 washers, making it appropriate for production assembly, service work, or job-site stocking.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum construction with plain finish for lightweight, corrosion-resistant performance\u003c\/li\u003e\n  \u003cli\u003e0.129 inch inside diameter sized for standard 1\/8 inch blind rivets\u003c\/li\u003e\n  \u003cli\u003e0.375 inch outside diameter provides broad load distribution across the joint surface\u003c\/li\u003e\n  \u003cli\u003e0.06 inch thickness maintains a low profile while adding backing strength\u003c\/li\u003e\n  \u003cli\u003eRound shape ensures consistent bearing area regardless of rivet orientation\u003c\/li\u003e\n  \u003cli\u003e250-piece pack supports bulk service and production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style backup washer for use with standard 1\/8 inch diameter blind rivets in sheet metal, HVAC ductwork, paneling, and general light-gauge fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by the trade installing the primary fastener — typically sheet metal workers, HVAC technicians, or general construction trades. Place the washer over the rivet mandrel on the blind side of the workpiece before setting the rivet with a standard rivet gun. Ensure the inside diameter clears the rivet body freely and that the workpiece surfaces are clean and properly aligned before pulling the mandrel. Refer to applicable structural or mechanical codes when blind rivet connections are used in load-bearing or code-governed assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRivet Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.129 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 250 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 34100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715148382514,"sku":"34100","price":19.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/501cf42bcc39ac87a4f23d24a022bb50.jpg?v=1788509760","url":"https:\/\/voomisupply.com\/products\/value-collection-34100-blind-rivet-backup-washer-1-8-in-250pk","provider":"Voomi Supply","version":"1.0","type":"link"}
