Powerbuilt Zeon hex key wrenches are designed to grip and turn damaged and rounded hex head fasteners. The patented design will grip and turn hex surfaces up to 85% rounded. In other words, if you've got a hex head bolt or cap screw bolt that's too damaged to turn with a regular hex bit socket or hex key wrench, these wrenches will get you out of a fix. And they work just as well on new, undamaged fasteners. The secret is the patented Zeon design - the more you turn them the harder they grab and hold damaged hex heads. They're constructed of hardened 8660 steel for maximum strength and durability. They feature extra-long handles for applying torque to those stubborn fasteners. For added versatility, the long handle wrench ends are finished with a ball end hex key for use on new fasteners at angles up to 20 degrees.

• TOP QUALITY: Premium SNCM-V steel with a satin finish that meets or exceeds ANSI standards
