Proto J10039L Impact Socket 1 in Drive 2-7/16 in 6-point

Product Description

The PROTO J10039L is a 1-inch drive, 6-point impact socket designed for heavy-duty fastener work in industrial, mechanical, and construction environments. Built from alloy steel, it delivers the toughness required to handle high-torque impact wrench output without cracking or deforming. The socket opening measures 2-7/16 inches across flats, with a hex drive configuration and an overall length of 4-7/8 inches. It meets ASME B107.2 standards, making it a reliable choice for shops and field crews that require certified tooling for critical applications.

This socket is suited for use in heavy equipment repair, fleet maintenance, structural assembly, and industrial manufacturing where 1-inch drive impact tools are standard. The 6-point contact geometry reduces the chance of fastener rounding under high torque loads, making it appropriate for rusted, tight, or high-cycle applications. Licensed mechanics, millwrights, ironworkers, and maintenance technicians are the primary users of drive tooling in this size class.

Key Features

• 1-inch drive size compatible with heavy-duty impact wrenches
• 2-7/16 inch socket opening in a 6-point hex configuration
• Alloy steel construction for impact and torque resistance
• Meets ASME B107.2 specification for impact sockets
• 4-7/8 inch overall length for reach in standard mounting positions
• Limited lifetime warranty from the manufacturer

Compatibility

Designed as an OEM-style replacement and general-use impact socket for 1-inch drive impact wrenches used in industrial and heavy mechanical applications.

Installation Notes

Install and remove only with a compatible 1-inch drive impact wrench or breaker bar rated for the torque demands of the application. Do not use impact sockets with standard hand-drive ratchets, as the wall thickness and metallurgy differ from chrome hand sockets. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Always wear appropriate PPE when operating impact tools.
