New self-clinching, threaded microPEM® TackScrew™ (Type TS™) fasteners enable cost effective sheet-to-sheet attachment, by simply pressing into place. The TackScrew™ fastener securely attaches a top sheet or panel to the base material. TackScrew fasteners can be removed by simply unscrewing similar to other threaded fasteners.

Features and Benefits
  • Simple, press-in installation for secure attachment
  • Proven clinch technology resists vibrational loosening.
  • Replaces micro screws, eliminating installation issues including:
    – Cost of locking patch
    – Cost of threaded insert or tapped hole
    – Cost of driver bits
    – Cost of rework due to cross-threading and driver bit “cam-out”
  • Can be installed automatically for high volume application.
  • Twists out (unscrew) if removal is necessary.Can be reinstalled one time using a thread locking adhesive.
Ideal for today’s compact electronics
  • Laptops
  • Notebooks
  • Tablet Computers
  • Cell/Smart Phones
  • Gaming / Hand Held Devices
  • Wearables
  • Automotive Electronics
