Backup washers are used in blind rivet installations to distribute clamping load and prevent pull-through on soft, thin, or oversized hole substrates. The KP7931 is sized for use with 1\/4-inch diameter blind rivets and measures 0.26 inches inside diameter, 0.5 inches outside diameter, and 0.06 inches thick. The plain aluminum finish offers adequate corrosion resistance for general-purpose indoor and sheltered applications. Installation of these washers is performed by sheet metal workers, HVAC technicians, and general fabricators during panel assembly and ductwork fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThis washer is suited for residential and light commercial applications where blind rivets are used to join sheet metal panels, ductwork sections, equipment enclosures, or similar thin-gauge assemblies. The 0.5-inch outside diameter provides a wide bearing surface relative to the 1\/4-inch rivet shank, helping secure fasteners in materials prone to deformation under pull-through load. The 50-piece package quantity makes this item practical for service van stocking and small-batch fabrication work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSized for 1\/4-inch diameter blind rivets with 0.26-inch inside diameter\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 bearing surface without adding significant stack height\u003c\/li\u003e\n  \u003cli\u003ePlain aluminum construction resists corrosion in general indoor and sheltered environments\u003c\/li\u003e\n  \u003cli\u003e50-piece package quantity suits service stock and small fabrication runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/4-inch diameter blind rivets in general sheet metal, ductwork, and light fabrication applications where backup support is required at the blind side of the joint.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePlace the backup washer on the blind side of the workpiece before setting the rivet, ensuring the washer seats flat against the substrate surface.
