Keystone Threaded Products US016AG1A002545 Hex Nut

Product Description

The KEYSTONE THREADED PRODUCTS US016AG1A002545 is a heavy hex nut machined from Grade 303 stainless steel for use in Acme-threaded fastener assemblies. It features a 1-5 inch Acme thread size with a 2G fit class and right-hand thread direction. At 1-5/8 inches (1.6250 inches) across the flats and 63/64 inches in height, this nut is sized for large-diameter threaded rod and power screw applications. Grade 303 stainless offers good corrosion resistance and machinability, making it a common choice in industrial, mechanical, and process-equipment installations. Mechanical contractors and industrial maintenance technicians are the typical installers.

This hex nut is suited for industrial and mechanical applications where Acme thread forms are specified, such as linear motion assemblies, jack screws, lead screws, and heavy mechanical linkages. It is appropriate for both new fabrication and replacement service in environments where stainless steel is required for corrosion resistance or material compatibility. The 2G fit class indicates a general-purpose Acme thread tolerance, balancing ease of assembly with acceptable positional accuracy under load.

Installation Notes

Installation should be performed by qualified mechanical or industrial maintenance personnel familiar with Acme thread systems and large-diameter fastener assemblies. Verify thread fit class and direction before assembly to avoid cross-threading. Use an appropriate open-end or box wrench sized to 1-5/8 inches across the flats. De-energize and lock out any equipment before servicing threaded fastener components under load.
