Wera 840/4 IMP DC Impaktor bits SB
Wera's 840/4 IMP DC Impaktor bits are 50mm hex bits built for impact drivers, with a diamond-particle coating that bites into the screw head and Hex-Plus geometry that increases contact area to prevent rounding. They suit mechanics and home-shop users driving hex hardware with an impact driver, in 4, 5 and 6mm sizes on a standard 1/4 inch drive.
- High quality Impaktor bits for hexagon socket screws.
- Impaktor technology offers an above-average service life even under extreme circumstances.
- Enhanced friction resistance, 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.
- 1/4'' hexagon, suitable for holders as per DIN ISO 1173-D 6.3.
