The right choise for
With the Facom STM.6 screwdriver socket bit, you can apply strong manual torque to metric socket head screws with total confidence. Unlike standard L-shaped keys that can easily slip, the precision-machined 6 mm hex bit seats securely into the screw head to prevent rounding and damage. Its sturdy 1/2" square drive connects directly to your manual ratchet or accessories, making it ideal for automotive repairs, mechanical assembly, and industrial maintenance. Featuring a compact 60 mm length and a fixed, non-removable bit design, it delivers outstanding control, direct power transfer, and easy access in tight working spaces.
