Utoolmart 12-Inch Drive by 19mm Shallow Impact Socket Cr-V 6-Point Metric 2 Pcs

* Made of chrome vanadium steel construction for strength and durability. * With black electrophoresis 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, automotive repairs, household maintenance, and most general repairs.
