Proto J5232N 1 Inch 12-point 3/8 Drive Hand Socket

Product Description

The PROTO J5232N is a 1-inch, 12-point intermediate hand socket built for professional hand-tool use in mechanical, industrial, and maintenance applications. Constructed from steel with a polished finish, this socket features a 3/8-inch drive and a standard-length design measuring 1-47/64 inches overall. The 12-point geometry allows engagement on fasteners from multiple angles, which is useful in confined spaces or when working with damaged or rusted hardware. It meets ASME B107.21 standards and carries a lifetime warranty, making it a dependable choice for tradespeople who rely on their hand tools daily.

This socket is suited for residential, commercial, and light industrial maintenance tasks where a 3/8-inch drive set is the preferred platform. Typical applications include equipment assembly, HVAC component fastening, plumbing fixture work, and general mechanical repairs. The standard length profile fits most common socket wrench, ratchet, and extension configurations used in field and shop environments.

Installation Notes

This socket is installed and removed by hand using a 3/8-inch drive ratchet, breaker bar, or torque wrench. Ensure the fastener size matches the 1-inch socket before applying torque to avoid rounding. Inspect the socket for cracks or wear before each use. Not tether capable — secure the work area appropriately when working at elevation or over open equipment.
