It is designed to distribute clamping load around a blind rivet, preventing pull-through in soft, thin, or fragile base materials. With a 3\/16 inch inner diameter, a 1\/2 inch outer diameter, and a thickness of 1\/16 inch, this washer fits standard 3\/16 inch blind rivets. This package contains 500 pieces. Installation is performed by sheet metal workers, maintenance technicians, and general fabricators working with pop-style rivets in production or repair applications.\u003c\/p\u003e\n\u003cp\u003eBackup washers of this type are used wherever a rivet must anchor into a material that would otherwise allow the rivet mandrel head or body to pull through the surface. Common applications include HVAC ductwork assembly, sheet metal enclosures, electrical panel fabrication, and light structural fastening. The zinc-plated finish provides baseline corrosion resistance suitable for indoor and protected outdoor environments. The 500-piece pack quantity supports production-volume work or stocking needs for active service operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/16 inch inner diameter sized for standard 3\/16 inch blind rivets\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch outer diameter spreads load to reduce pull-through in thin substrates\u003c\/li\u003e\n  \u003cli\u003e1\/16 inch thickness maintains a low profile in the fastened assembly\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel construction provides corrosion resistance for protected environments\u003c\/li\u003e\n  \u003cli\u003e500-piece pack quantity supports high-volume fastening work\u003c\/li\u003e\n  \u003cli\u003eRound washer profile compatible with standard rivet guns and installation tooling\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 Size 6, 3\/16 inch diameter blind rivets in sheet metal, HVAC, electrical enclosure, and general fabrication applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSheet metal workers and general fabricators typically install rivet backup washers as part of standard blind rivet assembly. Place the backup washer against the blind side of the work material before setting the rivet to distribute pull force across the washer face. Verify that the inner diameter clears the rivet body without binding prior to setting. No special tooling beyond a standard rivet gun is required for installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize Code\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRivet Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches (1\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 500 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 8.05 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: RIVETKING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SBUP-6\/P500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RIVETKING","offers":[{"title":"Default Title","offer_id":51965962682674,"sku":"SBUP-6\/P500","price":52.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e986f088a51dd281dfd40deecab8ffb.jpg?v=1789950124","url":"https:\/\/voomisupply.com\/products\/rivetking-sbup-6-p500-blind-rivet-backup-washer-500-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
