ALLEN BIT SW5 1/4″ L25MM

Hex socket bit C 6.3 (1/4) Powerdriv
ALLEN SW5 BIT 1/4 L25MM

C 6,3 (1/4″) POWERDRIV
Με POWERDRIV

The force is distributed to the convex surfaces on each side of the hexagon
This reduces the load on the screw and the bit
Without POWERDRIV

The force is only applied at individual points
Result: higher point load on the screw and the tip
