Two simple steps done with low-cost tooling--punch and anvil.
Step 1

Drill or punch recommended hole size in product material. Place PlugNut® on top of hole and locate in line with press punch and anvil.
Step 2
Press nut into hole. Use sufficient pressure to properly seat head by slightly embedding the head a few thousandths into the surface of the component material.

Applications:
Four Plugnuts in the corners of this stamped bracket hold it securely in place when the bracket is assembled with screws to its mating part in a submarine torpedo.
A Plugnut that takes a thumb screw provides a wear-resistant thread in cap for holding graphite molds used in cable splicing.
