Keystone Threaded Products NG020AC1A006345 Precision Acme Nut

Product Description

The KEYSTONE THREADED PRODUCTS NG020AC1A006345 is a machinable round precision Acme nut manufactured from gray iron. It stands 2.5 inches high and features a right-hand thread direction with a single thread start, conforming to a 2C class of fit. Gray iron construction provides good machinability and wear resistance, making this nut suitable for lead screw and linear motion assemblies where precise thread engagement is required. Installation and final machining are typically performed by machinists or mechanical trade professionals working on industrial or fabrication equipment.

This precision Acme nut is designed for use in linear motion systems, lead screw assemblies, and positioning mechanisms where controlled, low-friction thread engagement is critical. The 2C class of fit designation indicates a standard precision grade appropriate for general-purpose Acme thread applications. The machinable gray iron body allows the installer or machinist to bore, face, or otherwise finish the nut to exact bore dimensions required for a specific lead screw diameter and application. It is suited for both light industrial and fabrication shop environments.
