TEKTON 1/2 Inch Drive x 18 mm Hex Bit Socket | SHB23218

TEKTON bit sockets are formed through a carefully controlled insert process that press-fits S2 steel bits into the sockets for a straight, permanent connection that can't loosen over time. The 6-sided hexagonal tip is machined to precise tolerances for an exact fit with hex fasteners. Its chamfered end easily slides into fasteners, reducing wear. Die-stamped markings are permanently impressed into the steel and can’t wear off. They’re designed with large, clear size numbers that are easy to read even in low light settings. The bit socket'spolished chrome plating protects against corrosion and wipes clean to a mirror finish. The deepest parts of the socket well, where nickel and chrome layers cannot be deposited in sufficient thickness, are protected with an additional thin layer of clear coat, rather than conventionally-used silver paint, to prevent rust.
