Proto J5028B Deep Hand Socket 7/8 in 12-point

Product Description

The PROTO J5028B is a deep hand socket designed for 3/8 inch drive ratchets and breaker bars. Built from alloy steel with a black oxide finish, this 12-point socket measures 7/8 inch in size and 2.75 inches in overall length. The deep configuration provides the clearance needed to reach fasteners on extended studs, threaded rod, and recessed bolt heads. HVAC technicians, plumbers, electricians, and general service professionals keep sockets like this on hand for maintenance and installation tasks where standard-depth sockets fall short. It meets ASME B107.1 standards and carries a limited lifetime warranty.

The J5028B suits residential and commercial service applications where a 7/8 inch fastener is encountered on extended or recessed hardware. Common use cases include equipment mounting, panel work, pipe flange fasteners, and mechanical assembly tasks. The 12-point geometry engages fastener flats at multiple positions, useful in tight spaces where full ratchet swing is limited. This socket is not tether capable and is sold individually.

Installation Notes

This socket is installed by hand tool professionals across HVAC, plumbing, electrical, and mechanical trades. Confirm the fastener size matches 7/8 inch before applying torque to avoid rounding. Ensure the socket is fully seated on the drive before use. Inspect the socket for cracks or wear before each use and remove from service if any damage is found.
