Proto J5276HAM 13 Mm 6-point 3/8 Drive Hand Socket

Product Description

The PROTO J5276HAM is a 13 mm, 6-point hand socket designed for 3/8 inch drive ratchets and breaker bars used in mechanical and industrial service work. Built from alloy steel with a chrome-plated finish, this socket features a universal/flex socket type that allows access to fasteners at angles where a rigid socket cannot reach. At 1.75 inches overall length, it is a compact tool suited for tight quarters. The 6-point geometry provides full-face contact on hex fasteners, reducing the risk of rounding. It meets ASME B107.5M standards for hand socket dimensions and performance.

This socket is suited for automotive, fleet maintenance, and general mechanical service applications where 13 mm hex fasteners are common. The universal/flex design makes it particularly useful in engine bays, undercarriage work, and other confined spaces where straight-line socket access is restricted. It is sized for use with standard 3/8 inch drive hand tools including ratchets, extensions, and torque wrenches commonly found in professional tool sets.

Installation Notes

Installation and removal of fasteners with this socket should be performed by qualified mechanics or tradespeople familiar with hand tool safety practices. Ensure the drive connection is fully seated before applying torque. Do not use impact drivers with a hand socket rated for hand-tool use only. Inspect the socket for cracks or wear before each use and replace if deformation is present.
