Proto J10070M Impact Socket 1 in Drive 70mm 6-point

Product Description

The PROTO J10070M is a heavy-duty 1-inch drive impact socket designed for high-torque fastener removal and installation in demanding trade and industrial applications. Built from alloy steel, this 70mm hex drive socket features a 6-point contact pattern that maximizes surface engagement on fastener flats, reducing the risk of rounding under impact load. The overall length measures 3-53/64 inches, keeping the socket compact enough for use in tight drive-train and heavy equipment service environments. Licensed HVAC technicians, millwrights, fleet mechanics, and industrial maintenance techs will find this socket well-suited for large-diameter fastener work where impact gun compatibility is essential.

This socket is intended for use with 1-inch drive impact wrenches in commercial, industrial, and heavy-equipment service settings. Typical applications include drivetrain work, large machinery assembly, structural fastening, and heavy HVAC equipment installation where fastener sizes reach 70mm. The 6-point hex drive geometry makes it appropriate for standard hex-head fasteners at this size range. It meets ASME B107.33M specifications, confirming dimensional and performance compliance for professional use.

Key Features

• 6-point contact pattern reduces fastener rounding under high-torque impact loads
• Alloy steel construction for durability in heavy-duty impact service
• Overall length of 3-53/64 inches for compact reach in confined spaces
• Meets ASME B107.33M dimensional and performance standards
• Limited lifetime warranty coverage

Compatibility

Designed as an OEM-style professional-grade impact socket for use with 1-inch drive impact wrenches requiring a 70mm hex drive socket in industrial and heavy-equipment service applications.

Installation Notes

Installation and removal should be performed by qualified mechanics or tradespeople familiar with 1-inch drive impact tooling. Always ensure the socket is fully seated on the drive anvil and the fastener before applying torque. Inspect the socket for cracks or deformation before each use and remove it from service if damage is found. Never use impact sockets with hand-drive ratchets, as the different steel temper creates a fracture risk.
