Thread Masking Plugs for Self-Clinching Nuts and Standoffs

Protect internal threads during paint and powder coating processes.

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 ÂĽ-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.
