Abstract (en)
The bit (25) or the like is adapted for use in a driver (10) having a polygonal cavity, enabling the driver (10) to be tilted during use in tightening or loosening the bit (25). The bit (25) is elongated and has two sets of six driving surfaces (31, 36) equiangularly oriented about its longitudinal axis. The driving surfaces (31, 36) of one set are inclined at +10 DEG to the longitudinal axis, and the driving surfaces of the other set are inclined at -10 DEG to the longitudinal axis.
