Proto J5320B Deep Hand Socket 5/8 in 12-point 1/2 in Drive

Product Description

The PROTO J5320B is a deep hand socket designed for professional-grade fastener work in tight or recessed applications. Built from alloy steel with a chrome finish, this socket accepts a 1/2 inch drive and fits 5/8 inch fastener heads. The 12-point geometry allows engagement from more rotational positions, which is useful in confined spaces where swing arc is limited. At 3-1/4 inches overall length, it provides the reach needed for deeply recessed bolts and studs. Licensed tradespeople across mechanical, HVAC, plumbing, and electrical work will find this socket suited for equipment service, panel work, and general mechanical repair.

This socket is intended for hand-tool use in both residential and commercial service environments. It fits standard 1/2 inch drive ratchets, breaker bars, and extensions. The deep length makes it a go-to for wheel hardware, engine bay fasteners, conduit fittings, and any application where a standard-length socket cannot reach the full fastener depth. It meets ASME B107.1 standards, confirming dimensional and strength compliance for professional hand tool use.

Installation Notes

This socket is a hand-tool accessory and does not require installation in the traditional sense. Before use, confirm the drive size of your ratchet or breaker bar matches the 1/2 inch drive on this socket. Do not use impact drivers or impact wrenches with this hand socket unless the tool is rated for impact use. Inspect the socket for cracks or deformation before each use and replace if worn.
