Abstract

A bit 1 for a screwdriver comprises a secondary bit component 5 coupled to a primary bit component 3 for engaging with a screw head, the primary and secondary bit components 3, 5 being moveable relative to one another, the primary bit component 3 comprising a plurality of screw head engaging members 9, 11 that are moveably coupled to one another, each comprising distal regions such as blades 15, 17 remote from the secondary bit component 5 that are configured to mate with part of a screw head, such that movement of the secondary bit component 5 towards the primary bit component 3 urges at least one of said screw head engaging members 9, 11 to move relative to the other to increase a distance between their respective distal regions 15, 17. The secondary bit component 5 may include a plunger 45 and a ramp 47 to engage with a lateral wall 37 of one of the screw head engaging members 9, 11. The bit may take several forms such as a flat blade, a Hex wrench, square bit (fig. 8).
