Wera 3840/4 Bits, stainless, 4 x 89 mm

High quality bits out of stainless steel for hexagon socket screws. Wera stainless are made out of stainless steel which prevents the formation of unsightly extraneous rust. 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. ¼" hexagon, suitable for holders as per DIN ISO 1173-F 6.3.
