Bits Wera 840/1 Impaktor

High quality Impaktor bits for socket head cap screws. Impaktor technology provides extra long life even in extreme conditions. Increased frictional resistance thanks to the coarse diamond particle coating on the bit tip prevents the tool from slipping out of the screw. Hex-Plus provides as larger contact surface against the screw head. Voltage concentration is reduced to a minimum, which also reduces the risk of damage to the screw head. 1/4'' hexagonal, for holders according to DIN ISO 1173-D 6.3.
