TEKTON 3/8 in. Drive 12 mm 6-Point Deep Socket

Designed to apply maximum torque, the 6-point opening of the TEKTON 3/8 in. Drive 12 mm Deep Socket snugly fits the hex shape of fastener heads, so there is no opportunity for slipping. To prevent round-off, it grips the flat sides of fasteners rather than the corners. With an extra-deep broach, it reaches over long, threaded shafts to access nuts. Detent notches inside the drive end securely lock the socket onto ratchets and extensions, so it will not fall off or stick on fasteners. Made from premium chrome vanadium steel, it is protected from rust and corrosion by a durable, mirror chrome plated finish.
