Proto J10020T Impact Socket 1 in Drive 1-1/4 in 12-pt

Product Description

The PROTO J10020T is a 1-inch drive, 12-point impact socket designed for heavy-duty fastener work in industrial, mechanical, and trade service environments. Built from steel with a chrome finish, it accepts a 1-inch drive impact wrench and fits 1-1/4 inch fasteners. The overall length is 2-11/16 inches, keeping the profile compact for tight-clearance applications. The 12-point configuration provides multiple engagement positions around the fastener, which speeds up socket placement in production or field repair settings. This socket is a standard tool for journeymen mechanics, millwrights, heavy equipment technicians, and commercial HVAC or plumbing service crews working with large fasteners.

This socket is suited for use in commercial and industrial settings where 1-inch drive impact tools are standard equipment. Typical applications include equipment assembly, structural fastener installation, heavy machinery maintenance, and large-diameter pipe flange work. The 1-1/4 inch socket size is common on structural bolts, flange hardware, and heavy mechanical equipment. It is appropriate for both shop use and field service where a high-torque impact drive is required.

Installation Notes

Installation and removal of this socket should be performed with the drive tool powered down and the work area secured before engaging or removing the socket from the drive anvil. Ensure the socket is fully seated on the drive anvil before applying torque. Inspect the socket for cracks or wear before each use, as impact sockets subjected to repeated high-torque cycles can develop stress fractures. Use only with impact-rated drive tools — do not use this socket with hand ratchets where impact-rated clearances are not required.
