Proto J07541MT Impact Socket 3/4 in Drive 41mm 12-point

Product Description

The PROTO J07541MT is a 12-point impact socket designed for heavy-duty fastener work in professional trades and industrial maintenance. Built from alloy steel, it accepts a 3/4 inch drive and fits 41mm fasteners, making it well-suited for large bolts and nuts found in mechanical, construction, and industrial equipment. The overall length is 2.5 inches, providing a compact profile that fits into tighter clearances than deep-well alternatives. Mechanics, millwrights, and equipment technicians rely on this socket with high-torque impact wrenches where hand-tool sockets would crack or deform under load.

This socket is used in commercial and industrial applications where 41mm fasteners appear on heavy equipment, trucks, agricultural machinery, and structural assemblies. The 3/4 inch drive size is standard on mid- to heavy-range impact wrenches common in fleet shops, manufacturing floors, and field service environments. The 12-point geometry allows engagement from more angles, which is useful in confined work areas where socket placement is limited.

Key Features

• 3/4 inch drive fits standard mid- and heavy-duty impact wrenches
• 41mm socket size for large fastener applications on heavy equipment
• 12-point design allows greater positioning flexibility during installation and removal
• Alloy steel construction resists cracking and deformation under high-torque impact loads
• 2.5 inch overall length suits standard-reach applications without excess bulk

Compatibility

Designed as a direct-fit impact socket for 3/4 inch drive impact wrenches requiring a 41mm, 12-point socket in professional mechanical and industrial service applications.

Installation Notes

Install and remove using a 3/4 inch drive impact wrench or breaker bar rated for the torque required by the fastener application. Never use impact sockets with standard hand-ratchet sets not rated for impact loads, as this can cause tool failure or injury. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
