Proto J5422M 1/2 in Drive 12-point Hand Socket 22 Mm

Product Description

The PROTO J5422M is a 22 mm, 12-point hand socket designed for 1/2 inch drive ratchets and breaker bars. Machined from alloy steel with a chrome-plated finish, it provides corrosion resistance and a clean surface for regular shop use. The standard-length profile measures 1-17/32 inches overall, making it a straightforward fit for general mechanical and maintenance work. The 12-point design allows engagement at 30-degree intervals, offering more ratchet positions in tight spaces without sacrificing grip on fastener flats. It meets ASME B107.110-2012 and AS4984A standards, making it appropriate for professional tool inventories in automotive, industrial, and general mechanical trades.

This socket is suited for use in automotive repair, fleet maintenance, industrial equipment service, and general mechanical assembly. The 22 mm size is common on metric fasteners found on engines, suspension components, and structural hardware. The 1/2 inch drive interface pairs with standard impact-rated or hand-drive ratchets, extensions, and adapters. It is a conventional stock item for professional mechanics, millwrights, and maintenance technicians working on metric-fastened equipment in both shop and field environments.

Installation Notes

Hand sockets should be used with appropriately rated 1/2 inch drive hand tools only unless the socket is rated for impact use. Inspect the socket for cracks or deformation before each use and retire any damaged socket from service. Always ensure the socket is fully seated on the fastener before applying torque to avoid rounding the fastener or damaging the socket. Do not use cheater bars or pipe extensions on standard hand-drive ratchets.
