Proto J10070ML Impact Socket 1 in Drive 70mm 6-point

Product Description

The PROTO J10070ML is a heavy-duty impact socket designed for high-torque fastening and removal applications in industrial, fleet, and maintenance environments. Built from alloy steel, this socket features a 1 inch drive and accepts a 70mm hex fastener with a 6-point contact pattern that reduces rounding on worn hardware. The overall length measures 5 inches, providing clearance in recessed or tight mounting positions. Licensed trades and heavy equipment technicians reach for this socket when standard chrome sockets are inadequate for impact driver output.

This socket is well suited for heavy truck, mining, agricultural, and industrial equipment service where large-diameter fasteners are common. The 70mm socket size targets wheel hub assemblies, large bearing retainers, and structural bolting found in commercial and off-highway machinery. A 6-point drive geometry concentrates torque evenly across fastener flats, reducing slippage under sustained impact load. It is sized for use with 1 inch drive impact wrenches and drive accessories.

Key Features

• 1 inch drive fits standard heavy-duty impact wrenches and extensions
• 70mm socket size for large hex fasteners on heavy equipment and truck components
• 6-point contact pattern reduces fastener rounding under impact torque
• Alloy steel construction rated for impact tool use
• 5 inch overall length provides reach in recessed fastener applications

Compatibility

Designed as an OEM-style replacement or direct-use impact socket for 1 inch drive impact wrenches and manual breaker bars requiring a 70mm hex socket.

Installation Notes

This socket should be installed and removed by a qualified mechanic or maintenance technician. Always power down or de-energize the impact wrench before changing sockets, and confirm the retaining pin or locking mechanism is fully engaged before applying torque. Do not use impact sockets with standard ratchets or torque wrenches unless rated for that use. Inspect the socket for cracks or wear before each use and remove from service if damage is found.
