SOMS Series - Sink-O-Mask™ Plugs

  • Masking Through Holes and Surrounding Washer Area
  • Sink-O-Mask™ Plugs Feature Pull Tab for Easy Removal After Coating
  • 600°F (315°C)

Product Decription:

The Sink-O-Mask™ (SOM™) should be used where it is necessary to protect both a through hole and its surrounding washer area. The tapered design of the flange resists lifting at the edges for a clean finish.

Helpful Hints:

  • When plugging a hole, make sure that the plug diameter is larger than the diameter of the hole being plugged by at least 5%.
