This Draper TX-STAR® Tamperproof soft grip screwdriver set offers a selection of popular sizes. Each screwdriver has a hardened chrome vanadium steel round blade with chrome plating for corrosion protection. The blade tips are magnetic to hold the screw in place, making it easier to deliver more accurate force and precise fastening and loosening. The tips also have a black phosphate coating for added durability. They are fitted with an ergonomic soft grip comfort handle with drive type colour identification. The handle shape helps ensure the screwdrivers do not roll off flat surfaces.
