What are Bifix caps?

Bifix caps are press-in "star" caps that work in both Phillips Head and Pozidriv screws (hence the name: Bi- Fix)

Bifix caps are ideal for use on no-vibration applications where the security of the fastener and cap is not critical, such as

  • Cabinets
  • Furniture
  • Shopfitting
  • Kitchens
  • Cupboards

Why are Bifix caps so much better ?

Most "star" caps rely on an interference (or friction) between the sides of the driver recess and the wings of the cap stem.  This only works well if the driver recess is close to tolerance.  In practice, on an 8 gauge countersunk screw, tolerances can vary by 20% (even more on some imported screws), so 4-point star caps will often be too loose or too tight.  Further, although similar in many ways, the size of the drive recesses of Phillips Head and Pozidriv screws are substantially different, and one "star" cap cannot fit both types of screws

How do Bifix caps work?

The Stem:  Bifix caps have a patented 16 spline stem, which gains its grip in the central "circular" part of the drive recess.  This guarantees a good grip in both Phillips and Pozidriv screws, as well as out-of-tolerance, burred and damaged screws - Better than any other "star" cap on the  market.  Because of the nature of how the plastic splines deform to get this exceptional grip, Bifix caps should only be used once or twice for best results.

The Crown:  Bifix caps utilise the same low-profile crown used on Stemfix caps.  This means the cap is less noticeable and importantly, when the cupboard is being washed or wiped clean that cloths won't snag on the edges of the caps.  The underside of the crown is slightly concave to allow for screws that have not been driven flush with the work-surface.  The crown is flexible to ensure the smoothest transition from the work-surface to the cap.
