Hex bit sockets with FOUR FLAT sides: four parallel flats deter rolling, are wrench-compatible and create a slim profile for the best access in tight spaces. The one-piece design eliminates the risk of the bit separating from the socket base. Laser engraved size markings make identification easy, and chrome plating resists rust and corrosion. Stored on the included rail.
