Proto J5324B Deep Hand Socket 3/4 in 12-point 1/2 in Drive

Product Description

The PROTO J5324B is a deep hand socket designed for professional-grade fastener work in demanding trade environments. Built to a 3/4 inch socket size with a 1/2 inch drive, this 12-point socket provides added engagement points for turning standard hex fasteners in tight or awkward positions. The deep configuration accommodates extended bolts, studs, and recessed fasteners that a standard-length socket cannot reach. Constructed from alloy steel with a black oxide finish, it resists corrosion and reduces glare in low-light work areas. The J5324B meets ASME B107.1 standards and carries a limited lifetime warranty, making it a reliable choice for mechanics, millwrights, pipefitters, and general maintenance trades.

This socket is suited for residential and commercial maintenance, mechanical repair, and heavy equipment service where deep-reach fastener access is required. The 1/2 inch drive pairs with standard ratchets, breaker bars, and torque wrenches in that drive size. Typical applications include engine work, structural bolting, pipe flange fasteners, and equipment assembly. The 12-point design works with both standard and metric hex fasteners when the appropriate socket size is matched to the fastener.

Installation Notes

This socket is installed and used by mechanics, millwrights, and maintenance technicians working on mechanical and structural fasteners. Ensure the drive connection is fully seated on the ratchet or torque wrench before applying load. Inspect the socket for cracks or deformation before each use and do not use impact drivers with hand sockets unless the socket is rated for impact use.
