The TEKTON 1/2 in. Drive Round Head Ratchet is a proven classic. It is made from premium chrome vanadium steel that is hardened and strengthened through a precise heat treating process. To start fasteners, or quickly spin them when they are loose, the compact, round head features an integrated thumb wheel with a nonslip, knurled edge. The tough, full chrome plated finish resists rust and corrosion. Round and smoothly contoured, the fully polished handle offers a comfortable grip.
