Proto J10056 Impact Socket 1 in Drive 3-1/2 in 6-point

Product Description

The PROTO J10056 is a 1-inch drive, 6-point hex impact socket designed for heavy-duty fastener removal and installation. Built for use with 1-inch drive impact wrenches, this socket measures 3-1/2 inches across the hex and has an overall length of 4-1/2 inches. Weighing 8.56 pounds, it is constructed for the rigors of industrial and mechanical service environments. The 6-point contact geometry delivers maximum torque transfer while reducing the risk of fastener rounding under high-impact loading. This is a professional-grade tool used by mechanics, millwrights, and heavy equipment technicians.

This socket is suited for applications where large-diameter fasteners require high-torque impact driving. Common install scenarios include heavy equipment maintenance, agricultural machinery, commercial vehicle service, and structural fastener work. The 1-inch drive size places this tool in the heavy industrial category, typically found in fleet shops, mine sites, and large-scale manufacturing or construction maintenance operations.

Key Features

• 1-inch square drive for use with 1-inch drive impact wrenches and accessories
• 3-1/2 inch hex socket size for large-diameter fasteners
• 6-point design maximizes torque transfer and reduces fastener damage
• 4-1/2 inch overall length provides clearance in recessed fastener applications
• Heavy-duty construction rated for impact tool use

Compatibility

Designed as an OEM-style replacement and standard fitment for 1-inch drive impact wrench setups requiring a 3-1/2 inch, 6-point hex socket.

Installation Notes

This socket is installed and removed by licensed mechanics and heavy equipment technicians using 1-inch drive impact wrenches or breaker bars. Always ensure the socket is fully seated on the drive anvil and fastener before applying torque. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use impact sockets with hand-ratchet tools not rated for impact loads.
