Wera 868/1 Impaktor Square Robinson Screwdriver Bits

The Wera 868/1 Impaktor Square Robinson Screwdriver Bits are professional-grade impact driver bits designed for use with square socket screws, built to withstand the demands of heavy-duty site work. At the heart of these bits is Wera's Impaktor technology, which delivers above-average service life even under extreme working conditions — making these bits particularly well suited to use with impact drivers. Whether you're driving fixings into timber framing, decking, or structural applications, the bits are engineered to hold up where standard bits fail prematurely. A diamond-particle coating on the bit tip provides enhanced friction resistance, allowing the bit to literally bite into the screw head and prevent cam-out. This secure engagement is especially valuable when working at pace on site, reducing the frustration and lost time caused by slipping bits. The 1/4" hexagon drive (Wera connecting series 4) ensures compatibility with standard impact driver chucks and bit holders conforming to DIN ISO 1173-F 6.3. Wera's Take it Easy tool finder colour coding also makes identification quick and straightforward when working from a bit set or belt pouch.
