Proto J10022L Impact Socket 1 in Drive 1-3/8 in 6-point

Product Description

The PROTO J10022L is a 1-inch drive, 6-point hex impact socket designed for heavy-duty fastener removal and installation in demanding trade and industrial applications. Built for use with 1-inch drive impact wrenches, this socket measures 1-3/8 inches across the hex and 3-3/4 inches in overall length. The 6-point contact geometry distributes torque evenly across fastener flats, reducing the risk of rounding. Licensed mechanics, industrial maintenance technicians, and heavy equipment service professionals rely on this socket size for large-fastener work where standard hand-tool sockets are not rated for impact use.

This socket is suited for heavy equipment maintenance, fleet service, structural assembly, and industrial machinery repair where 1-3/8-inch fasteners are common. The 1-inch drive size places this tool in the heavy-duty segment, typically paired with large pneumatic or hydraulic impact wrenches found in commercial shops, mining, construction, and agricultural equipment service environments. It is a single-piece socket sold individually.

Key Features

• 1-inch square drive for use with heavy-duty impact wrenches
• 1-3/8 inch hex socket size for large fastener applications
• 6-point contact design reduces fastener rounding under high torque
• 3-3/4 inch overall length provides clearance in recessed fastener locations
• Impact-rated construction distinguishes it from hand-tool chrome sockets

Compatibility

Designed as an OEM-style impact socket for use with 1-inch drive pneumatic, hydraulic, or electric impact wrenches requiring a 1-3/8 inch, 6-point hex socket.

Installation Notes

Impact sockets should only be used with impact-rated drive tools. Before use, inspect the socket for cracks, deformation, or worn drive tangs and do not use damaged sockets. Ensure the retaining pin or locking mechanism on the impact wrench is fully engaged before applying drive pressure. This tool is intended for installation by qualified mechanics and maintenance technicians following applicable workplace safety standards.
