* To prevent rust and corrosion, the black phosphate finish absorbs and retains oil, repelling moisture.
* 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.
