micropem® tackpin®

What are your costs to design a screw?

  • Cost of screw
  • Cost of patch to prevent loosening
  • Cost of threaded insert or tapped hole
  • Cost of installation time - screw vs press
  • Cost of rework due to cross-threading
  • Cost of driver bits
  • Cost of rework due to driver bit “cam-out”
  • Is this less than $7k-12k?

TackPin® vs Screw

TackPin® vs Screw


  • Low-profile head
  • Interference fit eliminates hole tolerance
  • Tapered tip assists location
  • Positive engagement, 360 degree metal contact that will not loosen
  • Less weight


  • Costly tapping
  • Cross-threading
  • Torque control
  • Vibration back-out

Leather Cell Phone Case

No space is available for loose screws so a T4 TackPin® was used.

Highly cosmetic finish on the anodized aluminum buttons protected by coordinating both the fastener design and the install process.

PCB to Copper Busbar

TackPin® replaced adhesive.

Credit Card Reader

This customer was looking to streamline their card-reader dongle. Their new reader is 50% thinner than their original reader. One of the ways they were able to accomplish this was by eliminating two screws. This plastic reader is never repaired; it is simply replaced. Therefore, there is no need for a removable screw, and now their product is thinner, and easier to assemble.
