Proto J10054 Impact Socket 1 in Drive 3-3/8 in 6-point

Product Description

The PROTO J10054 is a 6-point hex drive impact socket designed for heavy-duty fastener work in industrial, mechanical, and trade service applications. Built from steel, it accepts a 1 inch drive and fits a 3-3/8 inch fastener. The overall length is 4-7/16 inches, placing it in the standard-length category. This socket is rated for impact driver use, making it suited for high-torque removal and installation tasks where hand-drive sockets would fail. Licensed mechanics, millwrights, pipefitters, and industrial maintenance technicians are the primary users of this tool class.

This socket is used wherever large-diameter fasteners are encountered: heavy equipment maintenance, structural steel assembly, pipeline flange work, pump and compressor service, and industrial machinery overhaul. The 6-point contact geometry reduces the risk of rounding fastener flats compared to 12-point designs, which is a practical advantage when working with worn or corroded hardware. Standard length suits most open-access fastener positions without requiring an extension.

Key Features

• 1 inch drive accepts standard heavy-duty impact wrenches and drive tools
• 3-3/8 inch socket size for large-diameter fastener applications
• 6-point hex drive geometry minimizes fastener rounding under high torque
• Standard overall length of 4-7/16 inches for direct-access fastener positions
• Steel construction rated for impact use

Compatibility

Designed as an OEM-style replacement and service socket compatible with 1 inch drive impact wrenches and ratchets in the standard heavy-duty drive class.

Installation Notes

This socket is installed and used by licensed mechanics, millwrights, and industrial maintenance technicians working with large-fastener assemblies. 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 on hand-drive-only ratchets or torque wrenches, as impact forces exceed their design ratings.
