Proto J10068L Impact Socket 1 in Drive 4-1/4 in 6-point

Product Description

The PROTO J10068L is a heavy-duty impact socket designed for use with 1-inch drive impact wrenches and rattle guns in professional trade and industrial maintenance applications. Built from alloy steel, this socket features a 6-point hex drive configuration and measures 4-1/4 inches across the socket opening with an overall length of 7 inches. The robust construction handles the high-torque output of pneumatic and electric impact tools without cracking or rounding fastener heads. Weighing 15.56 pounds, it is sized for large-fastener work typical in heavy equipment service, structural assembly, and industrial maintenance environments.

This socket is suited for commercial and industrial applications where large-diameter fasteners must be driven or removed under high torque. Typical use cases include heavy equipment repair, truck fleet maintenance, structural steel work, and industrial machinery service. The 6-point contact geometry reduces the risk of fastener rounding compared to 12-point designs, making it a reliable choice when working with worn or tight hardware. Trades commonly reaching for this socket include diesel mechanics, millwrights, ironworkers, and heavy equipment technicians.

Key Features

• 1-inch square drive fits standard heavy-duty impact wrenches and drive tools
• 4-1/4 inch socket size handles large-diameter fasteners common in industrial and heavy equipment work
• 6-point hex drive geometry maximizes contact area and reduces fastener rounding
• Alloy steel construction withstands repeated high-torque impact cycles
• 7-inch overall length provides reach in recessed or deep-set fastener applications

Compatibility

Designed for use with 1-inch drive impact wrenches and manual drive tools in heavy-duty industrial and commercial service applications.

Installation Notes

Installation and removal should be performed by a qualified mechanic or tradesperson familiar with high-torque impact tools. Ensure the impact wrench is rated for the torque requirements of the fastener before use. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use impact sockets with standard hand-drive ratchets, as impact-grade tools are required to safely handle the shock loads involved.
