Keystone Threaded Products UM016AG1A002565 Hex Nut

Product Description

The KEYSTONE THREADED PRODUCTS UM016AG1A002565 is a heavy hex nut with a 1-10 Acme thread profile machined from 1215 and 12L14 free-machining steel. It features a right-hand thread direction and a 2G fit class, which provides a practical balance of thread tolerance for general mechanical and industrial fastening applications. The nut measures 1.625 inches across the flats and 63/64 inch in height, weighing approximately 0.425 pounds. This part is suited for tradespeople and maintenance professionals assembling or repairing lead-screw mechanisms, linear actuators, and other Acme-thread assemblies.

This hex nut is intended for use in mechanical assemblies that rely on Acme-standard threaded components, such as lead screws found in industrial machinery, jigs, fixtures, and valve stems. Its 1215 and 12L14 steel grades offer good machinability and surface finish, making the part well-suited for applications where close thread engagement and smooth torque transfer are required. It is sold individually and is appropriate for both original equipment builds and field replacement work across a range of industrial and commercial settings.

Installation Notes

Installation is performed by qualified maintenance technicians or millwrights working on Acme-threaded lead-screw assemblies. De-energize and lock out all equipment before removing or installing threaded fasteners. Use an appropriately sized wrench matched to the 1.625-inch across-flats dimension to avoid rounding. Verify thread fit and engagement before applying final torque to ensure proper seating in the mating component.
