Rivetking. SBS66LF/P250 Open End Blind Rivet Size 66 250 Pack

Product Description

The RIVETKING. SBS66LF/P250 is a size 66 open end blind rivet with a large flange dome head, steel body, and steel mandrel, sold in a 250-piece package. It is designed for through-fastening applications where access is limited to one side of the workpiece. The body diameter measures 3/16 inches, the head diameter is 5/8 inches, and the grip range runs from 0.251 to 0.375 inches. The mandrel carries a phosphate finish. Tensile strength is rated at 680 pounds and shear strength at 540 pounds, making this rivet suitable for structural and semi-structural fastening in light- to medium-duty assemblies.

This rivet is used in sheet metal fabrication, HVAC ductwork assembly, electrical enclosures, and general industrial assembly where a wide-bearing flange head is needed to distribute clamp load across soft or thin substrates. The large flange dome head reduces pull-through risk in lower-density materials. It is installed using a standard blind rivet tool sized for 3/16-inch body diameter. The 250-piece package quantity suits bench stock and field service kits for contractors and maintenance trades.

Compatibility

Designed for use in standard 3/16-inch drilled or punched holes; recommended hole diameter range is 0.192 to 0.196 inches. Wire drill size No. 11 is the specified drill for hole preparation. Compatible with any manual or pneumatic blind rivet tool rated for 3/16-inch body diameter rivets.

Installation Notes

Installation is performed by a sheet metal worker, HVAC technician, electrician, or general maintenance mechanic using a blind rivet tool. Drill or punch the hole to the specified diameter range of 0.192 to 0.196 inches before inserting the rivet body. De-energize or lock out any live panel or assembly before riveting into enclosures or energized equipment housings. Do not exceed the maximum grip range of 0.375 inches, as insufficient material engagement reduces joint strength below rated values.
