Keystone Threaded Products UM016AG1A002540 Hex Nut

Product Description

The KEYSTONE THREADED PRODUCTS UM016AG1A002540 is a 1-4 Acme thread hex nut machined from 1215/12L14 free-machining steel. It features a right-hand thread with a 2G fit class, making it suitable for standard Acme lead screw and threaded rod applications where moderate thread tolerance and reliable engagement are required. The nut measures 1.625 inches across the flats and 63/64 inches in height, with a weight of 0.425 pounds. Installed by machinists, millwrights, and maintenance technicians, this nut is a direct-fit fastener for linear motion assemblies, jack screws, and general industrial threaded hardware.

This hex nut is designed for use in industrial and mechanical applications that require Acme-standard threading, including power transmission assemblies, positioning equipment, and linear actuator systems. The 1215/12L14 steel grade offers good machinability and surface finish characteristics, making it a common choice in production and maintenance environments where frequent disassembly or adjustment is anticipated. It does not meet military specifications and is intended for commercial and industrial use.
