Value Collection 34191 Open End Blind Rivet Size 66 100 Pack

Product Description

The VALUE COLLECTION 34191 is a size 66 open end blind rivet with a dome head, steel body, and steel mandrel, designed for permanent fastening applications where access is limited to one side of the workpiece. The body diameter measures 3/16 inches, with a grip range of 0.251 to 0.375 inches, making it suited for joining materials of varying thickness in a single pull cycle. With a tensile strength of 680 pounds and a shear strength of 540 pounds, this rivet meets IFI 114 Grade 30 standards. The mandrel carries a phosphate finish for corrosion resistance. Sold in a pack of 100, this rivet is installed by HVAC technicians, plumbers, sheet metal workers, and general maintenance professionals using a standard blind rivet tool.

This rivet is used in residential and light commercial applications where mechanical fastening of sheet metal panels, brackets, ductwork, and enclosures is required. The open end dome head design allows for flush, finished-looking joints on visible surfaces. A drill size of number 11 is required for hole preparation prior to installation. The 0.575-inch length under head accommodates typical sheet material stacking within the specified grip range.
