Proto J10064 Impact Socket 1 in Drive 4 in 6-point Hex

Product Description

The PROTO J10064 is a heavy-duty impact socket designed for use with 1-inch drive impact wrenches in professional trade and industrial applications. Built around a 4-inch hex socket with a 6-point contact pattern, it delivers high torque transfer while minimizing fastener rounding. The overall length of 5.5 inches accommodates deep or recessed fastener access. At 14.89 pounds, this is a solid, full-mass socket built for sustained impact use in demanding environments. Mechanical contractors, pipefitters, ironworkers, and industrial maintenance technicians are the primary users of sockets in this drive class.

This socket is suited for large-fastener applications where a 1-inch drive impact wrench is required, such as heavy equipment maintenance, structural steel assembly, large-diameter flange bolting, and industrial machinery service. The 4-inch hex size addresses oversized fasteners common in industrial piping, large HVAC equipment mounting, and utility infrastructure work. The 6-point drive geometry is preferred when high torque must be applied without slipping or damaging fastener surfaces.

Key Features

• 1-inch square drive compatible with industrial-class impact wrenches
• 4-inch hex socket size for large industrial and structural fasteners
• 6-point contact pattern for maximum torque transfer and reduced fastener wear
• 5.5-inch overall length for reach into recessed or deep fastener locations
• Heavy full-mass construction rated for sustained impact tool use

Compatibility

Designed as an OEM-style replacement and standard fitment for 1-inch drive impact tools used in industrial, mechanical, and heavy trade applications.

Installation Notes

Installation and service using this socket should be performed by qualified mechanical or industrial trade professionals. Always ensure the impact wrench and socket are rated for the torque demands of the application before use. Inspect the socket and drive retainer for cracks or wear before each use, and never use impact sockets with hand-drive ratchets. Follow applicable OSHA and site safety guidelines when working on heavy equipment or structural assemblies.
