Proto J15040L Impact Socket 1-1/2 in Drive 2-1/2 in

Product Description

The PROTO J15040L is a heavy-duty impact socket designed for use with 1-1/2 inch drive impact wrenches and air tools. Built from alloy steel, this 6-point hex drive socket measures 2-1/2 inches across and has an overall length of 6 inches, making it well-suited for high-torque fastening applications where a standard socket would fail. The 6-point geometry concentrates force on the flat faces of the fastener, reducing the risk of rounding. At 13.41 pounds, the J15040L is a substantial tool built for repeated industrial use. It meets ANSI specification B107.2 and carries a lifetime warranty.

This socket is suited for industrial, mechanical, and heavy equipment applications where large-diameter fasteners require controlled high-torque removal or installation. Typical install scenarios include mechanical rooms, industrial machinery, heavy-duty vehicle service, and large HVAC or refrigeration equipment assembly. It is used by licensed mechanics, millwrights, HVAC technicians, and industrial maintenance professionals working with oversized hex fasteners. The 1-1/2 inch drive size places this socket in the heavy industrial category, requiring a matching 1-1/2 inch drive impact wrench or breaker bar.

Key Features

• 1-1/2 inch drive size for use with heavy-duty impact wrenches and breaker bars
• 2-1/2 inch socket size for large-diameter hex fasteners
• 6-point hex drive geometry reduces fastener rounding under high torque
• Alloy steel construction for impact-rated durability
• 6 inch overall length provides clearance in recessed fastener applications
• Meets ANSI B107.2 specification
• Lifetime warranty

Compatibility

Designed as an OEM-style replacement and standard fitment impact socket for 1-1/2 inch drive impact tools requiring a 2-1/2 inch 6-point hex socket.

Installation Notes

Installation and removal should be performed by qualified mechanics or maintenance technicians familiar with heavy-duty impact tooling. Always ensure the drive tool is rated for 1-1/2 inch drive before use, and confirm the retaining pin or locking mechanism is fully engaged before applying torque. De-energize or shut down any powered equipment before accessing fasteners. Do not use adapters to reduce the drive size, as this can compromise torque transfer and create a safety hazard.
