Proto J10040 Impact Socket 1 in Drive 2-1/2 in 6-point

Product Description

The PROTO J10040 is a 1-inch drive, 6-point hex impact socket designed for high-torque fastener work in industrial, commercial, and heavy-equipment service applications. With a socket size of 2-1/2 inches and an overall length of 3-1/2 inches, this socket provides the clearance and drive engagement needed for demanding impact wrench use. Weighing 4.12 pounds, the J10040 is built to withstand the repeated shock loads generated by pneumatic and electric impact drivers. It is suited for mechanics, millwrights, and industrial maintenance technicians who require reliable, full-engagement drive tools for large-diameter fasteners.

This impact socket is intended for use in heavy-duty maintenance and repair operations where 1-inch drive impact tooling is standard. Typical applications include heavy truck and fleet service, industrial machinery assembly, structural steel work, and construction equipment maintenance. The 6-point drive geometry maximizes contact with fastener flats, reducing the risk of rounding under high torque. It is compatible with 1-inch drive impact wrenches commonly used in professional trade and industrial settings.

Key Features

• 1-inch drive size for use with heavy-duty impact wrenches
• 2-1/2 inch socket size for large-diameter fastener applications
• 6-point hex drive geometry maximizes contact and reduces fastener damage under high torque
• 3-1/2 inch overall length provides clearance in recessed fastener locations
• Rated for impact use — construction tolerates repeated shock loading from pneumatic or electric drivers

Compatibility

Designed as an OEM-style replacement and standard fitment for 1-inch drive impact wrenches used in industrial, fleet, and heavy-equipment service applications.

Installation Notes

Installation of this socket is performed by mechanics, millwrights, and industrial maintenance technicians using 1-inch drive pneumatic or electric impact wrenches. Always verify the socket is fully seated on the drive anvil and the retaining pin or ring is engaged before applying torque. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Follow applicable workplace safety standards and equipment manufacturer guidelines when working on machinery under load.
