TEKTON 3/8 in. Drive All Accessories Set (6-Piece) SIA91002 - 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 square bit tapers slightly towards the tip for easy insertion and strong engagement with fastener heads. Die-stamped markings are permanently impressed into the steel and cant wear off. They're designed with large, clear size numbers that are easy to read even in low light settings. 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
