Once a decade, an invention comes along that makes everyone totally revise the way that they think about an accepted form of technology. In the 1990s it was the Dyson vacuum cleaner. In the first decade of the twenty-first century it is set to be Uni-Screw, a revolutionary new screw and driver fastening system which substantially reduces tooling costs, improves assembly productivity and eliminates cam-out.
Uni-Screw was developed by engineers in Sheffield and is manufactured in the UK by Birmingham-based Forward Engineering. Uni-Screw is a direct replacement for Slotted, Phillips(TM), Pozi-Drive(TM) and Torx(TM) screws and offers significant advantages over these fixing media. As such it represents the most powerful development in screw fixing for decades.
Uni-Screw's unique design means one driver for screw size M2-M12
Uniquely, Uni-Screw uses the same driver for all sizes and so does not require any tool changes for screws between M2 and M12. (see Figure 2 and Plate 1). This is achieved because the Uni-Screw castellated driver locates tightly into the screw head, providing multiple drive surfaces, no matter what the size. For the smallest screw sizes, only the...
