Value Collection KP7873-1 Blind Rivet Size 43 100 Pack

Product Description

The VALUE COLLECTION KP7873-1 is an open end blind rivet with a large flange dome head, designed for one-sided fastening applications where access to the back of the joint is not possible. The body and mandrel are both steel, with a phosphate finish on the mandrel for corrosion resistance. This rivet measures 1/8 inch in body diameter with a 3/8 inch head diameter and accepts a grip range of 0.126 to 0.187 inches, making it suitable for a range of material thicknesses. Tensile strength is rated at 410 pounds and shear strength at 305 pounds. Each package contains 100 rivets. Electricians, HVAC technicians, plumbers, and general contractors commonly use blind rivets when installing sheet metal brackets, access panels, and equipment enclosures.

This rivet is suited for light to medium-duty fastening tasks in residential and commercial construction, HVAC ductwork, electrical panel work, and general sheet metal fabrication. The large flange dome head distributes clamping load over a wider surface area, making it a practical choice when working with softer substrates or thin sheet stock. The open end design allows the mandrel stem to pass through, which is the standard configuration for general-purpose blind riveting. Installation requires a standard rivet gun or pneumatic rivet tool matched to the 1/8 inch body diameter.

Compatibility

Designed as an OEM-style replacement or direct-use blind rivet for general sheet metal and structural fastening applications requiring a Size 43 open end rivet with a 1/8 inch body diameter and large flange dome head.

Installation Notes

Installation is performed using a hand-operated or pneumatic blind rivet tool sized for 1/8 inch body diameter rivets. Drill or punch the mating hole to between 0.129 and 0.133 inches per the specified hole diameter range before setting the rivet. Ensure the surfaces being joined are clean and free of debris for a proper set. Follow applicable building and mechanical codes, and wear appropriate eye protection during installation as mandrel stems eject upon setting.
