• 【Pin Hole】Individual pinhole base design adds extra security by placing in a locking pin for stability when exerting strong torque motion,.
• 【Widely Use】For disassembly and tightening of hexagon head bolts and nuts, especially suitable for requiring large torque and narrow space. The product has no insulation properties and is not suitable for electrical environments.

* 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.
