Above and beyond the ability of screws

While traditional micro screws can serve the general purpose of holding multiple components together, they can be an expensive option when considering the entire cost of your installation. Micro screws can also be a challenge to fit into smaller profiles and may increase the chance of failed performance within your application.

microPEM® solutions like TackPin® and TackSert® fasteners provide a better alternative by going above and beyond the ability of traditional micro screws: 

  • Smaller size – ideal for consumer electronics applications
  • Designed for thinner applications and a sleek cosmetic profile
  • Lighter and stronger
  • Fit within a smaller envelope
  • Lower total installed cost
  • Better process control
  • Reduced opportunities for field failures


Watch video comparing the microPEM® TackPin® Fastener to screw installation.

"We use a thread forming screw in our current generation of cameras. The head diameter is 4mm by 1.5mm and screw length is 6mm. The size of the TackSert® fastener was critical due to the reduction of our new camera size, clamp force requirements, cleanliness (thread forming screw required lubricant coating), and cycle time."

Which microPEM® Tack product is best for you?


Type TK Pins

  • Alternative to micro screws, eliminating many of the costs associated with threaded hardware
  • Simple, press-in installation. Does not require heat or ultrasonics
  • Appropriate for attaching top sheets to bases of cast aluminum, plastics such as ABS, or common magnesium die casting materials such as AZ91D
  • Top sheet can be any material
  • Ideal for circuit boards
  • Low-profile head fits places screws can’t
  • For use in cases in which disassembly is unnecessary

Self-Clinching Fasteners

  • Replaces and reduces costs associated with screws, welds, and adhesives.
  • Designed for sheet-to-sheet attachment.
  • For use in stainless steel and higher strength aluminum alloy sheets.
  • Attaches top sheets as thin as 0.2 mm / .008".
  • Clinches into base panel as hard as HRB 45 / HB 84.
  • Tapered and interference fit minimize hole tolerance issues.
  • Custom variations include countersunk, large head, flush head, this sheet and belleville-shaped FlexTack.
  • For use in cases in which disassembly is unnecessary.


  • 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.

  • Lowers overall total installed costs from the elimination of cost of screw, patch to prevent loosening, threaded insert or tapped hole and driver bits and cost of rework due to cross-threading or driver bit “cam-out”.
