Proto J7430MT Impact Socket 1/2 in Drive 30mm 12-pt

Product Description

The PROTO J7430MT is a 12-point impact socket designed for use with 1/2 inch drive impact wrenches and ratchets. Built for high-torque applications, it accepts a 30mm fastener and measures 2 inches in overall length. The 12-point configuration allows engagement from more positions around the fastener, making it useful in confined spaces where swing arc is limited. At 0.58 pounds, it is a solid, single-piece socket intended for professional use in mechanical, industrial, and heavy equipment service environments. Licensed tradespeople and experienced mechanics rely on impact-rated sockets like this one to handle the rotational force that standard chrome sockets are not designed to withstand.

This socket is suited for automotive, fleet, and industrial maintenance work where 30mm fasteners appear on wheel hubs, suspension components, drivetrain assemblies, and heavy equipment. The 1/2 inch drive size is a common standard in professional service bays and field repair kits, pairing with a wide range of impact guns, torque wrenches, and breaker bars already in use. It is appropriate for both shop and field applications.

Installation Notes

Impact sockets should be installed and removed by qualified mechanics or service technicians familiar with impact tooling. Always verify the socket is fully seated on the drive before applying torque. Do not use impact sockets with non-impact-rated accessories. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
