Proto J07531MT Impact Socket 3/4 in Drive 31mm 12-pt

Product Description

The PROTO J07531MT is a 12-point impact socket designed for heavy-duty fastener work in professional shop and field environments. It accepts a 3/4 inch drive and fits 31mm fasteners, with an overall length of 2.125 inches. Constructed from alloy steel, it is built to withstand the high-torque cycling of pneumatic and hydraulic impact wrenches. This socket is a standard tool for automotive technicians, industrial mechanics, and heavy equipment service professionals who need reliable performance on metric hardware.

The J07531MT is suited for use in automotive, fleet maintenance, industrial assembly, and heavy equipment applications where 31mm metric fasteners are common. Its 12-point design allows for six engagement positions per revolution, making it easier to position the socket in confined or awkward spaces. It is appropriate for both production environments and service bays where 3/4 inch drive impact tooling is standard.

Key Features

• 3/4 inch drive fits standard 3/4 inch impact wrenches and drive accessories
• 31mm socket size for metric fastener applications
• 12-point configuration provides multiple engagement positions for tight spaces
• Alloy steel construction handles repeated high-torque impact cycling
• Compact 2.125 inch overall length suits a range of fastener locations

Compatibility

Designed as an OEM-style replacement or service addition for 3/4 inch drive impact sets used on 31mm metric fasteners in automotive, fleet, and industrial maintenance applications.

Installation Notes

Installation is performed by qualified mechanics and technicians using 3/4 inch drive impact wrenches or breaker bars. Always confirm the socket is fully seated on the fastener before applying torque. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use hand-socket adapters to convert this impact socket for use with non-impact tools.
