The HAZET double ring spanner set 610N/8 in the long, slim design with ergonomically offset heads has different wrench widths on both sides. The shaft with extra-stable HAZET double-T profile is chrome-plated, the wrench heads are polished. The ring spanners (double hexagon) 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 enables 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.
