Proto J10039 Impact Socket 1 in Drive 2-7/16 in 6-point

Product Description

The PROTO J10039 is a 1-inch drive, 6-point hex impact socket designed for heavy-duty fastener removal and installation in industrial, mechanical, and construction environments. With a 2-7/16 inch socket size and an overall length of 3-25/64 inches, this socket delivers the wall strength and geometry needed to handle high-torque impact wrench output without rounding fastener heads. The 6-point design concentrates force on the flat sides of the fastener rather than the corners, reducing the risk of slippage under load. At 4.12 pounds, it carries the mass expected of a professional-grade 1-inch drive tool. Licensed mechanics, millwrights, and heavy equipment technicians are the primary users.

This socket is suited for large-fastener applications commonly found in heavy truck service, industrial machinery maintenance, structural steel assembly, and agricultural equipment repair. The 1-inch drive connection pairs with full-size pneumatic or hydraulic impact wrenches standard in fleet shops and industrial maintenance operations. The 2-7/16 inch hex size addresses fastener specifications common in drivetrain, suspension, and large-bore equipment work where standard 1/2-inch or 3/4-inch drive tools are undersized for the torque required.

Key Features

• 1-inch drive size for use with heavy-duty impact wrenches
• 2-7/16 inch socket size for large hex fasteners
• 6-point contact geometry reduces corner rounding under high torque
• Hex drive style for positive engagement on standard hex fastener heads
• Overall length of 3-25/64 inches provides reach without excessive overhang
• Weighs 4.12 pounds, consistent with full-thickness impact-rated construction

Compatibility

Designed as an OEM-style impact socket for use with standard 1-inch square drive pneumatic, hydraulic, or electric impact wrenches in professional trade and industrial service applications.

Installation Notes

This socket is installed and removed by qualified mechanics and industrial maintenance technicians using 1-inch drive impact equipment. Always confirm the socket is fully seated on the drive anvil and that 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 any damage is found. Do not use impact sockets on manual ratchets or torque wrenches, as impact-grade tools are designed specifically for percussive rotational loads.
