Socket

The Koken 3305M-8 is a deep 12-point socket designed for use with a 3/8-inch drive ratchet or breaker bar. It is engineered to reach into recessed fasteners or bolts where standard, shallow sockets cannot access. The deep length allows for sufficient engagement on longer bolts or studs. It is part of Koken’s deep socket series, known for precision engineering, durability, and excellent fit - ideal for mechanical, automotive, maintenance, and industrial applications.

Features:
12-point internal geometry allows engagement on more flats of the bolt head for easier alignment and greater grip.
Deep socket length (55 mm) to access bolts or studs recessed or protruding.
3/8-inch square drive input compatible with many ratchets, torque wrenches, and hand tools.
Precision machining to tight tolerances for good fit, reduced rounding of fasteners, and consistent performance.
Durable, hardened steel construction for strength and longevity under frequent use.
Finish suitable for resisting wear and corrosion to extend useful life of socket.
