Abstract (en)
[origin: EP1454712A2] The screwdriver bit (1) has a hexagonal shaft (5) and a head with four radial segments (6) and four concave gaps between them. The lower end (2, 3) is of a conical shape with a short pointed area (2) forming an acute angle (14) with the very tip. Each of the radial segments (6) is divided in a front (11) and a rear part (10) when looking at them in a clockwise direction. The front part is slightly wider (11) resulting in a tight fit with no tolerance.
