Description

* Made of chrome-moly steel construction for strength and durability.
* To prevent rust and corrosion, the black phosphate finish absorbs and retains oil, repelling moisture.
* 12-point opening is suitable for double hex (12-sided), hex and square fasteners, can grab fasteners quickly at multiple angles.
* To prevent round-off under stress, it grips the flat sides of fastener heads instead of the corners.
* The through-hole at the drive end locks on the tang of drivers or impact wrenches, so it wont fall off or stick on the fastener head.
* Widely used in DIY hand-making, household maintenance, and most general repairs.
