3840/1 TS bits, stainless, 5 mm x 25 mm x 1"

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. Come with Torsion zone: Torsion bits take-up torque peaks and absorb them in the Torsion zone. This prevents premature wear and extends the service life of the bit. 1/4" hexagon, suitable for holders as per DIN ISO 1173-D 6.3.
