Bit Standard 25 mm Internal Square Robertson #1, 2 pcs 1/4" in box - Wiha 38658

Robertson square drive screws are common in Canada and increasingly used in Europe, as the square profile transfers high torque with minimal cam-out risk. Wiha Standard bits #1 engage this screw type reliably thanks to a precision square profile of through-hardened chrome-vanadium steel. The tapered tip on the bit makes it easy to locate the screw head even with limited visibility. The reusable plastic box keeps the bits dust-free and protected from damage.
