Proto J47055LTM Deep Hand Socket 5 Mm 12-point 1/4 Drive

Product Description

The PROTO J47055LTM is a 5 mm, 12-point deep hand socket designed for use with 1/4-inch drive ratchets and extensions. Machined from alloy steel and finished with a chrome plating, this socket delivers corrosion resistance and durability in demanding shop and field environments. The deep-length design provides the additional reach needed to seat fully on fasteners with extended threads or recessed bolt heads. At 1-63/64 inches overall length, it fits into tight spaces while still clearing stud threads. Licensed tradespeople and service technicians working on mechanical assemblies, HVAC equipment, plumbing fixtures, and electrical panels will find this socket a reliable addition to a 1/4-inch drive set.

This deep hand socket is suited for residential and light commercial maintenance work where metric fasteners in the 5 mm range are common. Typical applications include equipment service, panel assembly, and mechanical fastener work requiring a 12-point engagement profile. The 12-point geometry allows more ratchet positions in confined spaces, reducing the arc needed for each stroke. It meets AS4984A and ASME B107.110-2012 standards, making it appropriate for professional trade use where tool certification matters.

Key Features

Compatibility

Designed as an OEM-style deep hand socket for use with 1/4-inch drive ratchets, extensions, and socket sets requiring 5 mm metric engagement.

Installation Notes

Install and remove with a calibrated 1/4-inch drive ratchet or torque wrench appropriate to the fastener specification. Ensure the socket seats fully on the fastener before applying torque to avoid rounding the drive points. Inspect the socket for cracks or wear before each use and remove from service if deformation is observed. This tool does not require special licensing to use but should be operated within the torque limits appropriate to the fastener material and grade.
