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

  • 1 Minimum sheet to prevent protrusion from through hole or minimum blind hole depth.
  • 2 The “L” dimension is the height of the installed stud at max grip. The height of the stud will increase if it is installed into thinner material. To calculate “actual L” use this formula: max grip - actual grip + L = “actual L”
  • 3 To minimize sheet distortion and maximize product performance, use a centerline-to-edge value greater or equal to the value specified.
