Wera 855/1 PZ BTH BiTorsion Extra Hard Pozi Screwdriver Bits

This variant is the PZ2 x 25mm Wera 855/1 BTH BiTorsion Extra Hard Pozi Bit, the most widely used Pozidriv size, making it an essential choice for general construction, joinery, and everyday fastening tasks. The PZ2 profile fits the broad range of standard Pozidriv screws, and the 25mm length provides compatibility with most common bit holders and power drivers. The BiTorsion zone works by dissipating kinetic energy at peak load points, greatly reducing breakage and extending bit life well beyond that of conventional alternatives. The extra-hard specification makes this bit particularly effective in semi-hard materials. Supplied as a single bit.
