Tekton SKT25101-D 1/2 Inch Drive 6-Point Socket and Ratchet Set with Case, 37-Piece (3/8 - 1-5/16 in.)TEKTON 6 point sockets are ideal for working with hex shaped fasteners. They're designed to grip the sides and not the corners of the fastener heads, which prevents round off. The large, die stamped markings are permanently impressed into the material and optimized for readability. A mirror chrome plated finish protects against corrosion and easily wipes clean. Included with the set is a sturdy, well marked case to keep the sockets securely organized.
