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”
