3840/1 TS bits, stainless
Wera Torsion Stainless screwdriver bits. Manufactured from Stainless Steel to prevent the formation of extraneous rust, then vacuum ice-hardened, ensuring the bits have the required hardness and strength needed for screw connections. The torsion zone absorbs peak loads from drill drivers, extending the service life of the bits. Drive tips with unique Hex-Plus profile; that drives from the flats instead of the points, preventing the rounding out off screws, whilst allowing 20% further torque to be applied (Hex-Plus profile fits every standard hexagon socket head screw). 1/4" hexagon drive (suitable for bit holders as per DIN ISO 1173-D 6.3). Take it easy tool finder; colour coding in accordance to profile and size, for fast & easy selection of the required bit.
