Proto J7431M Impact Socket 1/2 in Drive 31mm 6-point

Product Description

The PROTO J7431M is a 6-point impact socket designed for heavy-duty fastener removal and installation in professional trade environments. Built from alloy steel, it accepts a 1/2 inch drive and fits 31mm hex fasteners. The overall length is 2 inches, making it a compact, standard-depth option suited for tight quarters. The 6-point contact geometry distributes torque evenly across fastener flats, reducing the risk of rounding under high-impact loads. This socket is intended for use with 1/2 inch drive impact wrenches and rattle guns common in mechanical, HVAC, and industrial service work.

This socket fits typical applications where 31mm fasteners are encountered, including equipment mounting hardware, large pipe fittings, structural fasteners, and heavy machinery service. Its alloy steel construction handles the shock loads generated by pneumatic and electric impact drivers without deforming. Technicians working on commercial HVAC equipment, industrial plant maintenance, and heavy vehicle service will find this socket appropriate for daily production use. Package quantity is 1 socket per unit.

Installation Notes

Install and remove this socket only when the impact tool is depowered or the air supply is disconnected.
