Value Collection 34221 Dome Head Blind Rivet 1/8 in 100 Pack

Product Description

The VALUE COLLECTION 34221 is a dome head blind rivet designed for one-sided fastening applications where access to the back of the workpiece is limited or impossible. The rivet body is aluminum and measures 1/8 inch in body diameter with a length under the head of 0.328 inches. A steel mandrel provides the pulling strength needed to set the rivet. Grip range runs from 0.039 to 0.189 inches, making this rivet suitable for a variety of material stack thicknesses. Licensed contractors, mechanical tradespeople, and fabricators routinely use blind rivets where welding or bolt-through fastening is impractical.

This rivet is suited for light-duty metal fabrication, HVAC ductwork assembly, enclosure panel fastening, and general sheet metal work. The dome head profile sits flush against the surface material and distributes clamping load evenly. The 0.039 to 0.189 inch grip range accommodates single or multiple layers of sheet metal, plastic, or similar thin-gauge materials. Each package contains 100 rivets, making it appropriate for production runs or bulk service work. The aluminum body resists corrosion in typical indoor mechanical environments.

Installation Notes

Installation requires a hand, pneumatic, or battery-powered blind rivet tool with a 1/8 inch collet. Insert the rivet fully into the pre-drilled hole before setting. Apply steady, consistent pull force until the mandrel stem snaps cleanly at the break point. Inspect the set head on the accessible side to confirm full flare and uniform clamping before moving to the next fastener.
