Rivnut M4 Large Flange YP

Rivnuts (rivet nuts or nut inserts) are internally threaded, tubular fasteners that can be installed from one side of a workpiece (blind installation), providing strong, load-bearing threads in materials too thin for tapping. They are essentially permanent, vibration-resistant nuts installed using a special tool, ideal for metal, plastic, or fiberglass in automotive, industrial, and DIY applications.
