8Pc 3/8" Dr. SAE Zeon Hex Bit Socket Set

Powerbuilt Zeon hex bit sockets 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. And they work just as well on new fasteners.
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 that you can’t turn or a nut with rounded corners, we have the help you need. 
The secret is the patented Zeon bit socket design - the more you turn them the harder they grab and hold damaged hex heads. Zeon bit sockets are constructed of hardened S-2 Chromoly steel for maximum strength and durability.

• Zeon hex bit sockets grab and turn fasteners that are up to 85% rounded
• Work great on new fasteners too, without damaging them
• Heat-treated for extra hardness and bite
• Meets or exceeds ANSI standards
• Lifetime warranty
