Proto J10041M Impact Socket 1 in Drive 41mm 6-point

Product Description

The PROTO J10041M is a 1-inch drive, 41mm hex impact socket designed for high-torque fastening and removal applications in industrial and heavy-duty mechanical environments. Built with a 6-point drive style, it delivers concentrated force directly to fastener flats, reducing the risk of rounding under heavy load. The overall length measures 2-39/64 inches, keeping the profile compact for use in space-limited installations. At 2.07 pounds, the socket is built with the mass typical of impact-rated tooling. Licensed mechanics, industrial maintenance technicians, and heavy equipment service pros rely on this socket for production and field work.

This socket is suited for heavy-duty automotive, fleet maintenance, industrial machinery, and equipment assembly applications where a 1-inch drive impact wrench is standard. The 41mm size is common in large fastener applications found on commercial vehicles, agricultural equipment, and industrial assemblies. The 6-point geometry is preferred in professional trade settings where fastener integrity must be maintained during removal or installation at high torque.

Key Features

• 1-inch drive size for compatibility with heavy-duty impact wrenches
• 41mm socket size for large-format hex fasteners
• 6-point drive geometry reduces fastener rounding under high torque
• Compact 2-39/64 inch overall length for tighter access
• Impact-rated construction suited for pneumatic and electric impact tools

Compatibility

Designed as an OEM-style impact socket for use with 1-inch drive impact wrenches and torque tools in heavy-duty mechanical and industrial service applications.

Installation Notes

Installation and removal should be performed by qualified mechanics or industrial maintenance technicians familiar with impact tooling. Always ensure the socket is fully seated on the fastener and the drive tool before applying torque. Disengage power from the tool and verify the socket is locked onto the drive anvil before use. Do not use impact sockets with standard hand-drive ratchets, as impact-rated tooling is engineered specifically for the shock loads generated by impact wrenches.
