Proto J07518T Impact Socket 3/4 in Drive 1-1/8 in 12-pt

Product Description

The PROTO J07518T is a 12-point impact socket designed for heavy-duty fastener work in industrial, mechanical, and trade service environments. Built for use with a 3/4 inch drive impact wrench, this socket fits a 1-1/8 inch fastener and measures 2-3/16 inches overall length. The 12-point configuration provides multiple engagement positions on hex fasteners, reducing the need to reposition in tight quarters. Licensed tradespeople including mechanics, ironworkers, pipefitters, and millwrights rely on impact-rated sockets like this one for high-torque applications where standard chrome sockets would crack or fail under repeated impact loads.

This socket is suited for structural bolting, heavy equipment maintenance, and mechanical assembly work where a 3/4 inch drive impact tool is standard. The 1-1/8 inch size is common in flange bolting, equipment frames, and large fastener applications found in industrial and commercial settings. Its compact 2-3/16 inch overall length keeps it manageable in confined spaces without sacrificing drive depth or engagement.

Key Features

• 3/4 inch drive accepts standard 3/4 inch square drive impact wrenches and ratchets
• 1-1/8 inch socket size for large hex fasteners
• 12-point design for multiple engagement positions on standard hex hardware
• 2-3/16 inch overall length for use in moderate clearance applications
• Impact-rated construction handles high-torque power tool use

Compatibility

Designed as an OEM-style replacement or service socket for use with 3/4 inch drive impact wrenches and ratchets requiring a 1-1/8 inch 12-point socket.

Installation Notes

Impact sockets should only be used with impact-rated drive tools. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Never use impact sockets with a torque wrench unless the socket is specifically rated for that application. Follow applicable workplace safety standards and fastener torque specifications provided by the equipment manufacturer.
