Sized for 0.25 inch rivet diameter, this washer measures 0.26 inches inside diameter, 0.5 inches outside diameter, and 0.06 inches thick. The plain steel construction provides solid mechanical support in structural and sheet-metal fastening applications. Electricians, HVAC techs, plumbers, and general tradespeople working with blind rivets use backup washers like the KP7930 to prevent pull-through on thin or soft substrates where surface protection is needed at the blind side of the joint. Sold in a package of 50 pieces.\u003c\/p\u003e\n\u003cp\u003eThis backup washer is suited for residential and light commercial fastening work where 0.25 inch blind rivets are used on sheet metal panels, ductwork, enclosures, brackets, and similar assemblies. The washer seats against the blind side of the substrate, spreading the rivet mandrel load over a wider area to reduce the risk of material deformation or rivet pull-through. It is a standard consumable item kept on hand by trades professionals who regularly perform riveted panel and enclosure work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 0.25 inch rivet diameter with a 0.26 inch inside diameter for secure seating\u003c\/li\u003e\n  \u003cli\u003e0.5 inch outside diameter distributes clamping load across a wider surface area\u003c\/li\u003e\n  \u003cli\u003e0.06 inch thickness provides consistent standoff without excessive stack height\u003c\/li\u003e\n  \u003cli\u003ePlain steel construction suitable for general industrial and trade fastening applications\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 50 pieces supports production or service work without frequent reordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 0.25 inch diameter blind rivets in standard rivet gun applications across sheet metal, ductwork, enclosures, and light structural assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlace the backup washer on the blind side of the substrate before setting the rivet, positioning the washer so the rivet stem passes through the inside diameter.
