Thread Masking Plugs for Self-Clinching Nuts and Standoffs

Pem Pre Tect Thread Masking Plugs

PennEngineering’s new PEM PreTect thread masking plugs protect internal threads of self-clinching nuts and standoffs during paint and powder coating processes.

The pre-installed silicone masking plugs have been designed for self-clinching blind standoffs, thru-hole standoffs, and nuts in thread sizes #4-40 to ¼-20 and M3 to M6.

  • Plugs and film can be removed easily using a fine tip tool when processes are completed.

  • All self-clinching fasteners provide permanent and reusable load-bearing threads.

  • Stretched polyester film can offer thread protection on the side opposite the plug.
