Wera 840/4 IMP DC DIY 5 Piece 4.0mm x 50mm Hex-Plus Impaktor Bits

Application: Hexagon socket screws
Drive: 1/4" hexagon, suitable for DIN ISO 1173-F 6.3 bit holders
Design: The Impaktor technology ensures an above-average service life even under extreme conditions thanks to a best-possible utilisation of the material properties and optimally designed geometry, particularly suitable for use with conventional impact drivers, the rough diamond coating reduces the danger of any slipping out of the screw head due to the enhanced frictional resistance. Take it easy tool finder: Output colour coding (blue = hexagon) and large stamp to enable the desired bit to be easily located.

High quality Impaktor bits for hexagonal socket screws. The Impaktor technology offers an above-average service life even under extreme circumstances. Enhanced friction resistance, thanks to the rough diamond-particle coating on the bit tip, prevents any slipping out of the screw head. Hex-Plus ensures 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.
