The Groz Phillips Screwdrivers are manufactured from Chrome Vanadium, a high-grade steel that provides increased torque and wear resistance. The shaft extends into the handle, ensuring full transfer of force and maximum efficiency. These screwdrivers have a multi-component injection molded grip handle with a non-slip hexagonal design that provides an ergonomic and secure grip for transmitting higher torque. ¶The tip is magnetized and is hardened with a black oxide finish for enhanced corrosion resistance for durability. These are designed to fit into screws with a Phillips head.
