Proto J5431 Hand Socket 31/32 Inch 12-point 1/2 Drive

Product Description

The PROTO J5431 is a 12-point hand socket designed for 1/2 inch drive ratchets, breaker bars, and torque wrenches. Sized at 31/32 inch, it is built from alloy steel with a chrome plating that resists corrosion and makes cleanup easier in the field. The overall length is 1-9/16 inches, placing it in the standard-length category. This socket meets ASME B107.110-2012 and SAE AS4984A requirements, making it appropriate for use in professional maintenance, mechanical, and trade service work where dimensional and strength standards matter.

This socket fits general mechanical and maintenance applications across HVAC, plumbing, electrical, and industrial service environments. Its 12-point design allows engagement at 30-degree increments, which is useful in tight or obstructed spaces where swing arc is limited. The standard length profile keeps it compatible with a wide range of 1/2 inch drive extension bars and adapters. It is suited for both bench work and in-system fastener removal where a 31/32 inch fastener head is present.

Installation Notes

Install and remove with a 1/2 inch drive ratchet or torque wrench as appropriate to the fastener application. Confirm the socket is fully seated on the fastener before applying torque to prevent rounding. Do not use impact drivers with this hand socket unless it is rated for impact use. Inspect the socket for cracks or wear before each use.
