Value Collection KP7930 Blind Rivet Backup Washer 50 Pack

Product Description

The VALUE COLLECTION KP7930 is a plain steel round blind rivet backup washer used to distribute clamping load and protect the work surface during blind rivet installation. 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.

This 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.

Installation Notes

Place 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. Use a standard hand or pneumatic rivet tool appropriate for 0.25 inch rivets. Ensure the substrate and washer are flush and properly aligned before pulling the mandrel to avoid asymmetric load distribution.
