WERA 05073344001 840/1 Z SW 4.0/5.0/6.0 SET B SB BITS ASSORTMENT

Tough viscous Wera bits for hexagon socket screws in a practical 3-piece set, for universal use. The Hex-Plus profile offers a greater contact surface in the head of the screw. The notching effect is therefore reduced to a minimum and damage to the screw head more or less eliminated. 1/4" hexagon, suitable for holders as per DIN ISO 1173-D 6.3.
