These Draper TX-STAR screwdrivers have a hardened chrome vanadium steel round blade with chrome plating for corrosion protection. All sizes (except Stock No. 13560) have a hex bolster so they can be turned with a spanner for extra torque. The blade tip is magnetic to hold the screw in place, making it easier to deliver more accurate force and precise fastening and loosening. The tip also has a black phosphate coating for added durability. Comfortable moulded grip handle made from high impact resistant plastic, which is easy to clean and resistant to oils and chemicals. Its shape helps ensure the screwdriver does not roll off flat surfaces. There is a hang hole integrated into the handle for convenient storage.
