This hand-assembled screwdriver set is designed to fit standard wood screws. The set includes seven drivers, each with heavy square shanks. The drivers feature nickel-plated steel ferrules and chromium-vanadium 8650 alloy steel tips with black oxide finish. The square handles are made of quality hardwood and stamped with the size for quick identification. The blades are custom hollow-ground for precision fit and to prevent slipping under torque that may cause damage to the screw heads or surrounding surfaces.
