Proto J5232B 1 Inch 12-point 3/8 Drive Hand Socket

Product Description

The PROTO J5232B is a 1-inch, 12-point hand socket designed for professional mechanical and industrial applications. Built from alloy steel with a black oxide finish, it provides corrosion resistance and durability under daily shop use. The 3/8-inch drive fits standard ratchets and extensions commonly found in trade toolkits. At 1-3/8 inches overall length, this is a standard-length socket suited for most fastener access situations. Licensed mechanics, maintenance technicians, and industrial tradespeople rely on this type of socket for reliable torque transfer on hex and 12-point fasteners.

The J5232B is appropriate for use in automotive, HVAC equipment service, mechanical maintenance, and general industrial assembly where a 1-inch fastener must be driven with a 3/8-inch drive tool. The 12-point design allows engagement at 30-degree increments, which improves usability in tight or partially obstructed spaces. This socket is sold individually and is intended for hand-tool use with a matching 3/8-inch drive ratchet, breaker bar, or torque wrench.

Installation Notes

Hand sockets should be installed and removed by qualified mechanical or maintenance technicians. Always ensure the drive tool and socket are fully seated before applying torque to avoid rounding fasteners or damaging the drive square. Inspect the socket for cracks or wear before each use and do not use impact drivers with hand-rated sockets unless the socket is rated for impact use.
