Proto J10025L Impact Socket 1 in Drive 1-9/16 in 6-point

Product Description

The PROTO J10025L is a 1-inch drive, 6-point impact socket designed for heavy-duty fastener work in industrial, mechanical, and construction environments. Built around a hex drive style, it accepts a 1-9/16 inch fastener and delivers the torque transfer needed for impact wrench applications. At 4 inches overall length, it provides adequate reach for standard fastener access without excessive extension. Licensed trades and industrial mechanics rely on this socket class for high-torque tasks where hand-drive tools are not rated for the load.

This socket fits applications requiring a 1-inch square drive impact tool paired with a 1-9/16 inch hex fastener. Typical use cases include heavy equipment service, structural bolting, agricultural machinery, and industrial maintenance. The 6-point contact geometry concentrates load on the flat faces of the fastener, reducing the risk of rounding under high-torque impact conditions. It is suited for both shop and field use by mechanics and millwrights working with large fasteners.

Key Features

• 1-inch square drive accepts heavy-duty impact wrenches rated for that drive size
• 1-9/16 inch socket size for large hex fasteners common in industrial and heavy equipment applications
• 6-point hex drive geometry reduces fastener rounding under impact torque
• 4 inches overall length provides standard reach for accessible fastener positions
• Weighs 3.15 pounds, consistent with solid-steel impact socket construction

Compatibility

Designed for use with 1-inch drive impact wrenches and fits 1-9/16 inch 6-point hex fasteners. Intended as a direct-fit impact socket for industrial and heavy equipment service applications.

Installation Notes

Always match the socket drive size to the rated drive size of the impact wrench 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 on hand-ratchet drive tools, and do not use hand-drive sockets on impact tools. Retain the socket securely to the impact wrench using a hog ring or pin retainer appropriate for the drive size.
