TEKTON 1/2 in. Drive Extension Set, (4-Piece) (1-1/2,3, 6,10 in.) SHA92011 - The Home Depot

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 bit tips are machined to exact tolerances for precise engagement with fasteners. Die-stamped markings are permanently impressed into the socket with large, clear size numbers that are easy to read even in low light settings and can't wear off. The bit socket's polished 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. Included with the set is a sturdy, well-marked case to keep the sockets securely organized
