Made of high carbon steel material for wear resistance and durability. With black oxidized treatment to protect against rust and corrosion. It has a 6-point opening that fits tightly to the hexagonal shape of the fastener head, enabling it to apply maximum torque without slipping. To prevent round-off under stress, it grabs the flat sides of fastener heads instead of the corners. The through hole of the drive end is locked on the tang of the impact wrench or driver, so it will not fall off or stick to the fastener head. Suitable for nuts with small spacing. Widely used in DIY hand-making, household maintenance, and most general repairs.
