Proto J10062L Impact Socket 1 in Drive 3-7/8 in 6-point

Product Description

The PROTO J10062L is a 1-inch drive impact socket built for heavy-duty fastener work in industrial, mechanical, and trade service environments. Designed for use with 1-inch drive impact wrenches, it features a 3-7/8-inch socket opening and a 6-point hex drive geometry that delivers maximum torque transfer with reduced risk of rounding fastener heads. The socket is machined from alloy steel for durability under repeated impact loads. Overall length measures 6.375 inches, providing reach in recessed or tight fastener locations. This socket is typically installed and used by industrial mechanics, heavy equipment technicians, and experienced trade professionals.

This socket is suited for high-torque applications found in heavy equipment service, large-bore piping and flange work, structural assembly, and commercial vehicle maintenance. The 1-inch drive size places it in the heavy industrial category, intended for powered impact tools rated for that drive size. It is sold individually and is appropriate for shop or field use where large-diameter fasteners require controlled, repeatable torque application.

Key Features

• 1-inch drive size compatible with heavy-duty impact wrenches
• 3-7/8-inch socket opening for large-diameter hex fasteners
• 6-point hex drive geometry reduces fastener rounding under high torque
• Alloy steel construction rated for repeated impact loading
• 6.375-inch overall length provides reach in recessed fastener locations

Compatibility

Designed as an OEM-style replacement or direct-use impact socket for 1-inch drive impact wrenches requiring a 3-7/8-inch 6-point hex socket.

Installation Notes

This socket is installed and used by industrial mechanics and heavy equipment technicians operating 1-inch drive impact tools. Confirm the drive tool is rated for 1-inch drive before use, and ensure the socket is fully seated on the drive anvil before applying torque. Do not use impact sockets on non-impact ratchets or torque wrenches, as impact-rated tools and hand tools have different load tolerances. Inspect the socket for cracks or deformation before each use and retire any damaged socket from service immediately.
