Keystone Threaded Products UM032AG1A005040 Hex Nut

Product Description

The KEYSTONE THREADED PRODUCTS UM032AG1A005040 is a heavy hex nut designed for 2-4 Acme-threaded applications. Machined from 1215/12L14 free-machining steel, this nut features a right-hand thread with a 2G fit class, making it suitable for lead screw assemblies, linear actuators, and other precision power-transmission systems. It measures 3 inches across the flats and stands 1-31/32 inches in height. At 2.99 pounds, this is a substantial fastener intended for industrial and mechanical applications requiring reliable thread engagement under load. A licensed millwright, maintenance mechanic, or industrial technician is the typical installer.

This hex nut is used in mechanical assemblies where Acme thread forms are specified for power transmission or linear motion. Common applications include machine tool lead screws, jacking mechanisms, press assemblies, and industrial equipment that requires controlled linear movement. The 2G Acme thread fit class provides a standard-clearance engagement appropriate for general-purpose power-transmission use. The 1215/12L14 steel grade offers good machinability and is a standard choice in commercial fastener and threaded-component applications.

Installation Notes

Installation is typically performed by a millwright, machinist, or industrial maintenance technician. Ensure the mating lead screw or threaded rod is clean and free of burrs before engagement to protect the 2G thread fit. Use appropriate wrenching flats on the 3-inch hex profile - do not use pipe wrenches or adjustable tools that can deform the hex. Verify thread direction is right-hand before assembly to avoid cross-threading.
