Product Description

The KEYSTONE THREADED PRODUCTS NG012AC1A003845 is a machinable round precision Acme nut manufactured from gray iron. It features a right-hand, single-start thread in a 3/4 in - 5 Acme thread size with a 2C class of fit, making it suitable for applications that require controlled backlash and reliable linear motion. Standing 1.5 inches high with an overall diameter of 2.235 inches, this nut is supplied in a machinable condition so technicians and machinists can finish bore, face, or keyway to final application dimensions. It is used in lead screw assemblies across mechanical, industrial, and maintenance trade settings.

This precision Acme nut is intended for use in lead screw and power screw assemblies where moderate load capacity and accurate thread engagement are required. The 2C class of fit is a standard clearance fit appropriate for general-purpose linear actuation, jacks, vises, and machine slides. The machinable gray iron construction allows the installer or machinist to finish the nut to the exact bore and profile required by the mating assembly. It is a single-piece component sold individually and is a common choice for OEM fabrication, field repair, and replacement work in industrial and mechanical maintenance applications.
