New self-clinching microPEM® TackPin® (Type T4™)fasteners are ideal for installation into stainless steel and higher strength aluminum alloy sheets. They are for use in compact electronic assemblies enabling sheet-to-sheet attachment, replacing costly screw installation in applications where disassembly is not required. TackPin&reg fasteners eliminate typical screw-related issues (including tapping, cross-threading, torque control, and vibration backout) and ultimately promotes quick and easy installation with minimal hardware. TackPin&reg fasteners can provide a good alternative to welds or adhesives.

Features and Benefits
  • Advantages over micro screws: eliminates costly tapping, cross threading, torque control, vibration back-out and installation time.
  • Interference fit minimizes hole tolerance issues.
  • Tapered tip assists location.
  • Low-profile head provides space savings.
  • Can be installed automatically.
  • For use in stainless steel and higher strength aluminum alloy sheets..
