Proto J07521-LT Impact Socket 3/4 in Drive 1-5/16 in 6-pt

Product Description

The PROTO J07521-LT is a 6-point thin wall impact socket designed for heavy-duty fastening and removal tasks. It accepts a 3/4 inch square drive and fits a 1-5/16 inch hex fastener. The thin wall profile allows access to fasteners in recessed or tight clearance applications where a standard wall socket would not fit. With an overall length of 3.25 inches, it delivers the reach needed for common industrial, mechanical, and structural fastening work. This socket is built for use with 3/4 inch drive impact wrenches and is a standard tool for licensed mechanics, millwrights, pipefitters, and field service technicians working with heavy equipment or structural fasteners.

The J07521-LT suits applications in industrial maintenance, heavy equipment service, construction, and commercial mechanical work. The 6-point drive geometry reduces the chance of rounding fasteners under high torque impact loads compared to 12-point designs. The thin wall construction makes it appropriate for use in confined spaces such as engine compartments, structural steel connections, and equipment frames where standard sockets cannot seat properly. It is compatible with any 3/4 inch drive impact wrench or breaker bar.

Key Features

• 3/4 inch square drive fits standard heavy-duty impact wrenches and breaker bars
• 1-5/16 inch socket size for hex fasteners
• 6-point contact design reduces fastener rounding under high-torque impact use
• Thin wall profile provides clearance in recessed or tight-access fastener locations
• 3.25 inch overall length for added reach in deep or obstructed applications

Compatibility

Designed for use with 3/4 inch drive impact wrenches, air tools, and breaker bars requiring a 1-5/16 inch 6-point hex socket.

Installation Notes

This socket is installed and removed by hand as part of normal impact tool operation. Ensure the drive tool is depressurized or powered off before changing sockets. Inspect the socket for cracks or deformation before each use, particularly after high-torque impact applications. Do not use impact sockets with hand-ratchet tools not rated for impact loads.
