Proto J73104 Deep Impact Socket Set 8 Pc 3/4 in Drive

Product Description

The PROTO J73104 is an 8-piece deep impact standard socket set built for heavy-duty fastener work in demanding trade environments. Driven by a 3/4 inch drive, the set covers a size range from 1-1/16 inches to 2-3/8 inches, making it well suited for large-diameter fasteners found in mechanical, industrial, and construction applications. All sockets feature a 6-point design that maximizes contact area on hex fasteners, reducing the risk of rounding under high-torque impact loading. Constructed from steel and packaged in a cardboard box for organized storage, this set is a practical addition to any shop or field toolbox where large-format impact work is routine.

This socket set is intended for use with 3/4 inch drive impact wrenches and ratchets. The deep profile accommodates fasteners on extended studs, threaded rod, and recessed bolt applications common in structural steel assembly, heavy equipment maintenance, fleet service, and industrial machinery work. The eight included sizes span a range that covers many of the largest fasteners encountered in these settings, reducing the need to source oversized sockets individually.

Installation Notes

Installation and removal of large fasteners with this set is typically performed by millwrights, ironworkers, fleet technicians, and heavy equipment mechanics. Always verify that the drive tool torque rating is appropriate for the fastener specification before applying load. Inspect sockets for cracks or deformation before each use and remove any damaged sockets from service immediately. Do not use impact sockets with non-impact hand tools if the tool is not rated for the resulting torque.
