Abstract

A new design of screw head, the Uni‐screw, has been developed to rival the well‐established slotted, Phillips and Pozidriv screws. It is based on a series of hexagonal recesses that avoids “cam‐out”, which occurs with the other designs when higher torques are applied. Other benefits include the need for only one driver over a wide range of screw sizes and easy alignment of driver to screw. Other recess forms can be used including pentagon and heptagon to provide high tamper resistance, and these can be tailored for a single user to give total security. The Uni‐screw is being manufactured and distributed by Forward Engineering under a licence from Uni‐screw and the first commercial products are aimed at the building and DIY markets. Strong interest has also been shown by several industrial organisations.
