Proto J4712 Hand Socket 3/8 Inch 6-point Chrome

Product Description

The PROTO J4712 is a 6-point hand socket designed for precision fastener work in mechanical, industrial, and trade service applications. Built from alloy steel with a chrome-plated finish, it accepts a 1/4-inch drive and fits 3/8-inch fasteners. The standard-length design measures 7/8 inch overall, keeping it compact for work in tighter spaces. The 6-point geometry reduces the chance of rounding fastener corners compared to 12-point designs, making it a reliable choice for technicians working on stubborn or worn hardware. It meets AS4984A and ASME B107.110-2012 standards, confirming dimensional and performance compliance for professional use.

This socket is suited for light-duty mechanical service tasks where a 1/4-inch drive ratchet or extension is used. Common applications include HVAC component fasteners, electrical panel hardware, plumbing fixture work, and general equipment maintenance where 3/8-inch fasteners are encountered. The standard-length profile fits most open work areas. At 0.03 pounds, it adds minimal weight to a tool kit. Note that this socket is not tether-capable and is not intended for elevated or drop-sensitive work environments.

Key Features

Compatibility

Designed for use with 1/4-inch drive ratchets, extensions, and accessories. Fits 3/8-inch hex fasteners in standard service applications.

Installation Notes

Installation is performed by licensed mechanics, HVAC technicians, electricians, or experienced service professionals. Ensure the drive tool and socket are fully seated before applying torque to avoid slippage or fastener damage. Inspect the socket for cracks or wear before each use. This socket is not rated for tethered or overhead applications where dropped-tool hazards exist.
