Proto j5320 Deep Socket 5/8 in 12-point 1/2 in Drive

Product Description

The PROTO j5320 is a 12-point deep hand socket designed for SAE fastener work in professional trade and industrial settings. Built from alloy steel with a chrome finish, it accepts a 1/2 inch drive and fits 5/8 inch fasteners. At 3.25 inches overall length, the deep-well profile provides the clearance needed to reach recessed bolts, studs, and nuts that a standard-depth socket cannot access. This socket meets ASME B107.110-2012 and SAE AS954G standards, making it suitable for demanding hand-tool applications. It is not impact rated and is intended for use with manual drive tools only.

The j5320 is used in general-purpose mechanical maintenance and repair across HVAC equipment service, plumbing rough-in, electrical panel and equipment installation, and general industrial applications. The deep-well design is particularly useful when working on fasteners with exposed thread engagement or when clearing obstructions around a bolt head. The 1/2 inch drive connection is compatible with ratchets, breaker bars, torque wrenches, and extensions of the same drive size.

Installation Notes

This socket is intended for installation by qualified tradespeople using manual 1/2 inch drive tools only. Do not use with impact wrenches or air tools, as this socket is not impact rated.
