Proto J10068 Impact Socket 1 in Drive 4-1/4 in 6-point

Product Description

The PROTO J10068 is a heavy-duty impact socket designed for use with 1-inch drive impact wrenches and air tools. Built as a 6-point hex drive socket, it accepts a 4-1/4-inch fastener and measures 5.5 inches in overall length. The 6-point design concentrates force on the flat sides of the fastener, reducing the risk of rounding under high-torque impact loads. This socket is intended for licensed mechanics, industrial maintenance technicians, and trade professionals working on heavy equipment, truck assemblies, or structural fastener applications where large-diameter fasteners are common.

This socket is suited for heavy equipment maintenance, fleet service, industrial assembly, and structural bolting applications. The 1-inch drive size places it in the category of large-frame impact tooling, typically used on equipment with high-torque fastener requirements. It works with 1-inch square drive impact wrenches and fits into professional tool sets requiring large-format socket coverage.

Key Features

• 1-inch square drive for use with heavy-duty impact wrenches
• 4-1/4-inch socket size fits large-diameter hex fasteners
• 6-point contact geometry reduces fastener rounding under impact
• 5.5-inch overall length provides clearance in recessed fastener applications
• Designed for high-torque impact use in industrial and fleet service environments

Compatibility

Designed as an OEM-style replacement or direct-fit impact socket for 1-inch drive impact wrenches requiring a 4-1/4-inch 6-point hex socket.

Installation Notes

Installation and use should be performed by qualified mechanics or trade professionals familiar with large-drive impact tooling. Always verify the socket is fully seated on the drive anvil before applying torque. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use impact sockets with hand ratchets or torque wrenches, as impact-rated and hand-tool-rated sockets are not interchangeable.
