* Made of chrome vanadium steel construction for strength and durability.
* With black phosphate finish, to protect against rust and corrosion.
* Has 6-point opening that snugly fits the hex shape of fastener heads, allowing it to apply maximum torque without slipping.
* To prevent round-off under stress, it grips the flat sides of fastener heads rather than the corners.
* The through-hole in the drive end locks onto the tang of impact wrenches or drivers so it won't fall off or stick on fastener heads.
* Widely used in DIY hand-making, household maintenance, and most general repairs.
