The 30-piece socket wrench set 905 from HAZET impresses with its ergonomic design and comfortable handling thanks to tools arranged within easy reach. The tools and socket wrenches are optimally protected in the case with a 2-component soft foam insert. The set includes a reversible ratchet, a joint wrench, extensions and socket wrench inserts in various sizes. The hexagon inserts have the traction profile developed by HAZET specifically for wrenches and socket wrenches, without sharp edges or points. The enlarged contact surface of the traction profile in the wrench ensures secure transmission of the torque and reduces the notch effect to a minimum. This optimally protects the screw head from damage and corner wear. Even damaged and worn screws can still be safely loosened with the traction profile, as spinning or slipping is almost impossible.
