Abstract: A bit for removing a broken fastener comprises a tip from which extend two or more notches separated by traction or biting surfaces formed from two-sided frusto-conically-shaped regions. The surfaces are bounded on one side by a nonlinear cutting edge and on the other side by a non-cutting edge and are configured to cut into the fastener when the bit is rotated in a direction opposite to the fastener's direction of engagement. Specific embodiments include configurations where the cutting edges extend at different angles with respect to the bit axis, where the biting surfaces comprise a plurality of serrations, and where the cutting edges are separated by flutes which spiral along a longitudinally extending periphery of the bit.

Abstract: A multi-functional fastener driver device 10 that is capable of providing rotational force to fasteners having different configurations (hexagonal, flathead, wingnut or hook screw, for example) to urge a preselected fastener into a workpiece. The device 10 includes a first portion 12 that is secured, via a shank portion 16, to a tool providing rotary force, and a second portion 14 that transfers the rotary force to a preselected fastener via a plurality of arm members 30. The arm members 30 are configured from multiple apertures 24 and 38, and slots 32 and 34. The arm members 30 engage the fastener and force the fastener to rotate thereby “screwing” the fastener into the workpiece. When fasteners are to large to rotate without deforming the arm members 30, a sleeve 42 is utilized to snugly receive the device 10 therein to maintain the arm members 30 configuration while rotating the fastener. Further, the sleeve 42 includes opposing recesses 52 in an end wall 50.
