Proto J10058 Impact Socket 1 in Drive 3-5/8 in 6-point

Product Description

The PROTO J10058 is a heavy-duty impact socket designed for use with 1 inch drive impact wrenches and air tools. Built in a 6-point hex drive configuration, it accepts a 3-5/8 inch fastener and delivers the torque transfer needed for high-load industrial and mechanical applications. The overall length of 4-3/4 inches accommodates recessed fasteners and tight clearances without sacrificing drive engagement. Weighing 10.59 pounds, this is a substantial, professional-grade socket intended for demanding service environments. Licensed trades and industrial mechanics rely on this class of tooling for structural fastener work, heavy equipment maintenance, and fleet service.

This socket is suited for industrial, commercial, and fleet maintenance applications where large-format fasteners require controlled impact torque. Typical install scenarios include heavy equipment assembly, structural bolted connections, and large-diameter fastener removal or installation. The 1 inch drive size places this socket in the category of heavy-duty impact tooling used in construction, mining, transportation, and manufacturing maintenance environments. It is compatible with standard 1 inch drive impact wrenches and extensions.

Key Features

• 1 inch drive size for use with heavy-duty impact wrenches and air tools
• 3-5/8 inch socket opening fits large-format hex fasteners
• 6-point contact geometry reduces fastener rounding under high torque
• 4-3/4 inch overall length for reach into recessed fastener locations
• Designed for impact use, not hand-tool ratchets

Compatibility

Designed as an OEM-style replacement or service socket for use with standard 1 inch square drive impact wrenches and compatible drive extensions in heavy-duty mechanical applications.

Installation Notes

Installation and removal should be performed by qualified mechanics familiar with 1 inch drive impact tooling. Always ensure the impact wrench is rated for the torque demands of the fastener before use. Inspect the socket for cracks or deformation before each use, and never use impact sockets with hand-tool ratchets or torque wrenches. Secure the socket fully onto the drive anvil before applying torque to prevent slippage or ejection.
