Porcas Rebites

Rivet nuts, also called threaded inserts or blind rivet nuts, are blind fasteners that create load-bearing machine threads in thin sheet, tube, and extrusions when only one side is accessible. They eliminate welding and tapping, support dissimilar materials, and enable serviceable metal fastening with standard screws. Selection centers on hole geometry, head profile, and required torque and pull-out performance. Hex bodies in hex holes provide strong anti-rotation, knurled round bodies improve spin-out resistance in round holes, flat heads spread clamp load, and reduced heads fit tight clearances. Match material and finish to the environment and galvanic pairing, choose a grip range that covers total stack thickness, and follow hole prep and installation parameters for consistent results using hand or pneumatic tools.
