Proto J10038L Impact Socket 1 in Drive 2-3/8 in 6-point

Product Description

The PROTO J10038L is a 1-inch drive, 6-point impact socket designed for heavy-duty fastener removal and installation. With a 2-3/8 inch socket size and an overall length of 4-3/4 inches, this socket is built for use with 1-inch drive impact wrenches in demanding industrial, fleet, and construction applications. The 6-point hex drive geometry delivers solid contact across flat fastener faces, reducing the risk of rounding under high-torque impact conditions. Weighing 6.12 pounds, this is a robust, full-size socket suited for professional trades requiring reliable performance on large fasteners.

This socket is intended for use in applications where large hex fasteners are common, including heavy equipment maintenance, structural steel work, truck and trailer service, and industrial machinery repair. The 1-inch drive size places it in the range of high-capacity air and electric impact tools typically found in commercial shops, fleet service bays, and construction sites. Licensed mechanics, millwrights, and heavy equipment technicians are the primary users of this size class.

Key Features

• 1-inch drive size compatible with full-size industrial impact wrenches
• 2-3/8 inch socket opening for large hex fasteners
• 6-point contact geometry minimizes fastener rounding under impact torque
• 4-3/4 inch overall length provides clearance in recessed fastener applications
• Heavy construction at 6.12 pounds indicates robust wall thickness for impact-rated use

Compatibility

Designed as an OEM-specification 1-inch drive impact socket for use with standard 1-inch square drive impact wrenches and accessories.

Installation Notes

Install and remove using a 1-inch drive impact wrench or breaker bar rated for the torque demands of the application. Always verify the socket is fully seated on the fastener before applying torque to prevent slippage or fastener damage. Inspect the socket for cracks or deformation before each use, and retire any socket showing visible wear. Do not use impact sockets with standard hand-drive ratchets not rated for impact loads.
