Proto J07531M Impact Socket 3/4 in Drive 31mm 6-pt

Product Description

The PROTO J07531M is a 3/4 inch drive, 31mm hex impact socket built for high-torque fastening applications. It features a 6-point drive geometry that concentrates force on the flats of the fastener rather than the corners, reducing the risk of rounding under heavy impact loads. The overall length is 2-11/64 inches, making it suited for standard-depth fastener access. At 0.99 pounds, the socket is forged for durability while remaining practical for extended use. This socket is intended for use with 3/4 inch drive impact wrenches and is installed by mechanics, millwrights, pipefitters, and other trade professionals working in industrial, commercial, and heavy equipment environments.

This socket is appropriate for applications requiring metric fastener engagement on heavy-duty assemblies where standard chrome sockets are not rated for impact use. Typical use cases include equipment maintenance, structural fastening, and assembly line service where a 31mm hex fastener and a 3/4 inch drive impact tool are in play. The 6-point profile is preferred in professional trade settings where fastener integrity must be preserved under repeated high-torque cycling.

Key Features

• 3/4 inch drive size compatible with standard 3/4 inch drive impact wrenches and breaker bars
• 31mm socket size for metric hex fastener engagement
• 6-point drive style reduces corner loading and lowers risk of fastener rounding
• Overall length of 2-11/64 inches suits standard-reach fastening tasks
• Impact-rated construction designed to absorb repeated torque impulses without cracking or deforming

Compatibility

Designed as an OEM-style replacement or direct-fit socket for use with 3/4 inch drive impact wrenches, torque multipliers, and breaker bars requiring a 31mm 6-point hex socket.

Installation Notes

Impact sockets should be installed and operated by qualified mechanics or trade professionals familiar with high-torque tooling. Always confirm the socket is fully seated on the drive anvil and the retaining pin or hog ring is engaged before applying torque. Do not use impact sockets with hand-drive torque wrenches, as impact-rated materials are not calibrated for precision torque measurement. Inspect the socket for cracks or deformation before each use and remove from service if damage is observed.
