Proto J15670A Impact Universal Joint 1-1/2 in Male Female

Product Description

The PROTO J15670A is an impact-rated universal joint designed for heavy-duty socket drive applications in professional trades. Built to a 1-1/2 inches male and 1-1/2 inches female drive size, it delivers the angular flexibility required when working in tight or offset access points. A black oxide finish provides corrosion resistance under demanding shop and field conditions. The welded pin design adds structural integrity, keeping the joint together under the high-torque, high-vibration loads typical of impact wrench use. At 5-27/64 inches overall length, it fits standard deep-reach drive setups without excessive extension. This tool is specified to ASME B107.2, the governing standard for impact drive tools.

This universal joint is suited for use by mechanics, millwrights, pipefitters, and industrial maintenance technicians working with 1-1/2 inches drive impact equipment. Typical applications include heavy equipment service, industrial machinery maintenance, and structural fastener work where straight-line socket access is not possible. The 1-1/2 inches drive size places it in the heavy industrial and large-frame equipment service category rather than the light-duty automotive range.

Key Features

• 1-1/2 inches male and 1-1/2 inches female drive for heavy industrial applications

Compatibility

Designed for use with 1-1/2 inches drive impact wrenches and socket sets in heavy industrial service applications.

Installation Notes

Installation and removal of this universal joint should be performed with the equipment fully de-energized and any stored mechanical energy released. Inspect the joint for wear or deformation before each use, as impact-rated components subjected to overload may develop cracks not visible to the naked eye. Ensure the male and female drive connections are fully seated before applying torque. This tool is intended for use by qualified tradespeople familiar with 1-1/2 inches drive impact equipment and applicable workplace safety standards.
