This Wiha T-bit is ideal for screwing T-shaped screws with a 90° angle between the thread and the screw head. It features a patented, extended torsion zone making it suitable for impact and impact screwdrivers, offering a 120x longer service life than standard Wiha bits. The colored bits are easy to find, even in the dark with UV light, thanks to the color jacket, reducing lost bits and procurement costs.
