The Bellville washer shaped head of the microPEM® FlexTack™ fastener is designed to increase vertical installation tolerance in designs.

  • Alternative to using micro-screws, eliminating the need to tap or use threaded inserts.
  • Installation time to simply press the part in (1.5 seconds) is less than the time to thread a screw in equals less total installed cost.
  • The Belleville-shaped head allows for stack-up tolerance relief in a design.
  • Eliminates the following:

  • - Cost of screw, patch to prevent loosening, threaded insert or tapped hole and driver bits
    - Cost of rework due to cross-threading or driver bit “cam-out”
