Proto J10040L Impact Socket 1 in Drive 2-1/2 in 6-point

Product Description

The PROTO J10040L is a 1-inch drive, 6-point impact socket designed for heavy-duty fastener work in industrial, mechanical, and trade service environments. Built from alloy steel, this socket measures 2-1/2 inches across the hex drive opening and has an overall length of 4-7/8 inches. The 6-point geometry maximizes contact with fastener flats, reducing rounding under high-torque impact loads. At 6.28 pounds, it carries the mass expected of a full-size industrial impact socket. It meets ASME B107.2 specifications and is backed by a limited lifetime warranty. Licensed mechanics, industrial maintenance technicians, and heavy equipment service crews are the primary users of this tool.

This socket is suited for high-torque applications where a 1-inch drive impact wrench is required, such as heavy truck service, construction equipment maintenance, structural assembly, and industrial plant maintenance. The 2-1/2-inch socket size targets large-format fasteners common in those environments. The alloy steel construction holds up to repeated impact cycles without cracking or deforming under load.

Key Features

• 1-inch square drive for use with full-size industrial impact wrenches
• 2-1/2-inch hex socket size for large-format fasteners
• 6-point design maximizes surface contact and reduces fastener rounding
• Alloy steel construction rated for impact use
• 4-7/8-inch overall length provides reach in tight clearance applications
• Meets ASME B107.2 specification
• Limited lifetime warranty

Compatibility

Designed for use with 1-inch drive impact wrenches. Compatible with standard 1-inch drive impact tool anvils across major tool platforms.

Installation Notes

This socket is intended for use with a 1-inch drive pneumatic, hydraulic, or electric impact wrench only — do not use with standard hand-drive ratchets or breaker bars unless the tool is rated for impact service. Ensure the socket is fully seated on the drive anvil and the retaining pin or ring is secured before applying torque. Inspect the socket for cracks or deformation before each use. Wear appropriate PPE including eye protection when performing impact work.
