Proto J5320M Deep Hand Socket 20mm 1/2 Dr 12-point

Product Description

The PROTO J5320M is a deep hand socket designed for professional fastener removal and installation in demanding trade and industrial applications. Built to a 20 mm socket size with a 1/2 inch drive, this 12-point socket provides additional contact points for engagement on fasteners, which helps when working with worn or tight hex hardware. The chrome-plated finish adds corrosion resistance for shop and field use. The deep-length profile accommodates extended fastener shanks, studs, and recessed bolts that standard-depth sockets cannot reach. This socket suits licensed mechanics, pipefitters, millwrights, and maintenance technicians who require reliable hand-drive tooling.

The J5320M fits into general mechanical maintenance, HVAC equipment assembly and service, plumbing rough-in and mechanical work, and electrical panel or equipment installation where 20 mm fasteners are present. The deep configuration is particularly useful on equipment with long threaded studs or when working inside confined assemblies where clearance limits socket positioning. It is used as a hand-drive socket with a standard 1/2 inch ratchet, breaker bar, or torque wrench.

Key Features

• 20 mm socket size fits standard metric fasteners
• 1/2 inch drive accepts common ratchets, torque wrenches, and breaker bars

Compatibility

Designed as a standard-fitment 1/2 inch drive deep hand socket compatible with any 1/2 inch drive ratchet, torque wrench, extension, or breaker bar using conventional square-drive tooling.

Installation Notes

A licensed mechanic, pipefitter, or trained maintenance technician typically installs or removes fasteners using this socket. Always ensure the socket is fully seated on the fastener before applying torque to prevent rounding. De-energize or shut off any equipment before working on fastener connections associated with live electrical or pressurized mechanical systems. Inspect the socket for cracks or wear before each use and remove from service if damage is observed.
