Powerbuilt 9 Piece Zeon Metric Hex Key Wrench Set for Damaged Fasteners

The Powerbuilt Zeon hex key wrenches are specially designed to grip and turn damaged and rounded hex head fasteners, using a patented design that can grip and turn hex surfaces up to 85% rounded. These wrenches can solve the problem of hex head bolts or cap screw bolts that are too damaged to turn with a regular hex bit socket or hex key wrench. The patented Zeon design is effective on both new and undamaged fasteners, using a gripping mechanism that strengthens as you turn the wrench. The wrenches are made of hardened 8660 steel for maximum strength and durability, and their extra-long handles provide ample torque for stubborn fasteners. The long handle wrench ends are finished with a ball end hex key for use on new fasteners at angles up to 20 degrees, making them a versatile addition to any toolbox.
