Proto J07528MT Impact Socket 3/4 in Drive 28mm 12-pt

Product Description

The PROTO J07528MT is a 3/4 inch drive impact socket designed for heavy-duty fastener removal and installation in professional trade and industrial environments. Built from alloy steel, it features a 28mm socket size with a 12-point design and measures 2-1/8 inches overall length. The 12-point configuration provides increased contact points on fastener heads, reducing the chance of rounding under high-torque impact conditions. This socket is intended for use with 3/4 inch drive impact wrenches and is suited for mechanics, industrial maintenance technicians, and skilled tradespeople working on heavy equipment, fleet vehicles, and structural assemblies.

This socket fits typical applications where 28mm fasteners are encountered, including truck and heavy equipment drivetrain work, structural bolted connections, and industrial machinery maintenance. Its alloy steel construction handles the repeated shock loads generated by pneumatic and electric impact wrenches without deforming or cracking. The 3/4 inch drive size is standard in heavy-duty shop and field work where higher torque output is required compared to smaller drive sizes.

Key Features

• 3/4 inch drive for use with heavy-duty impact wrenches
• 28mm socket size handles large fasteners common in heavy equipment and fleet applications
• 12-point design provides more engagement positions for fastener access in tight spaces
• Alloy steel construction resists impact stress and wear under repeated high-torque use
• 2-1/8 inch overall length suits standard reach requirements without excessive bulk

Compatibility

Designed as an OEM-style replacement or direct-fit addition for 3/4 inch drive impact wrench sets requiring a 28mm 12-point socket.

Installation Notes

Installation and use of impact sockets should be performed by qualified mechanics or tradespeople familiar with impact tooling. Always use impact-rated sockets with impact wrenches — never substitute standard chrome hand-tool sockets, which can shatter under impact loads. Ensure the socket is fully seated on the drive anvil and fastener head before applying torque. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
