Proto J07522T Impact Socket 3/4 in Drive 1-3/8 in 12-pt

Product Description

The PROTO J07522T is a 12-point impact socket designed for heavy-duty fastener work in industrial, mechanical, and trade service applications. Built for a 3/4 inch drive, it accepts a 1-3/8 inch fastener and measures 2.25 inches in overall length. The 12-point configuration allows for greater rotational access in tight clearance situations, making it practical for equipment with limited swing room. At 1.21 pounds, this socket is sized for use with pneumatic and hydraulic impact wrenches common in fleet, industrial maintenance, and heavy equipment service environments. Licensed tradespeople and experienced mechanics are the primary installers.

This socket fits standard 3/4 inch drive impact wrenches and is suited for residential and commercial mechanical service work, including structural fasteners, heavy machinery assembly, and infrastructure maintenance tasks where a 1-3/8 inch fastener size is required. The 12-point geometry provides additional engagement positions compared to a 6-point design, which can be useful when working on fasteners in confined or awkward positions.

Key Features

• 3/4 inch drive size for compatibility with heavy-duty impact wrenches
• 1-3/8 inch socket size for large-format fastener applications
• 12-point design allows more drive positions in restricted spaces
• 2.25 inch overall length suited for accessible fastener locations
• Rated for impact tool use — not hand-tool-only service

Compatibility

Designed as an OEM-style replacement or direct-fit socket for 3/4 inch drive impact wrenches used in heavy-duty mechanical and industrial service applications.

Installation Notes

Installation and use of this socket should be performed by qualified mechanics or tradespeople familiar with impact tooling. Always ensure the impact wrench is powered down and depressurized before changing sockets. Confirm the socket is fully seated on the drive anvil and the retaining pin or ring is secure before applying torque. Do not use impact sockets with hand-ratchets or torque wrenches unless specifically rated for that use.
