Step 35Tri-Arc®
[[br]]Tri-ArcŪ is a new concept in screw head, a bits and driver design that has been comparatively tested to Crosshead design. The head has a recess that consists of three lobes. The recess is based on each lobe separate by curved drive flanges. The driver has a drive tip that fits the recess of the screw or fastener and sinks 2-3mm below the surface of the upper flange. The 3 curved surfaces give Tri-ArcŪ screws and fasteners more contact surface area and more surface pressure area.
The main advantages of this new design include increased resistance to cam out and reduction in wear and tear on its drivers compared to the Philips or Posidrive. The bit doubles up as a good countersinking tool.
These may not be on the open market as yet, as the inventor is requesting a company who can develop the product and/or is interested in a licensing agreement. [[br]]
