Keystone Threaded Products NG008AC1A002565 Acme Nut

Product Description

The KEYSTONE THREADED PRODUCTS NG008AC1A002565 is a machinable round precision Acme nut manufactured from gray iron. Standing 1 inch high with an overall diameter of 1.465 inches, this nut features a 1/2-10 right-hand thread and conforms to a 2C class of fit, making it appropriate for applications requiring controlled backlash and smooth linear motion. The single-start thread profile follows the standard Acme thread form. Its gray iron construction provides adequate compressive strength for moderate-load power transmission assemblies. Manufactured under ISO 9001:2019 quality standards, this nut is intended for installation by machinists, maintenance technicians, and mechanical assemblers working with lead screw and power transmission systems.

This Acme nut is suited for use in linear actuator assemblies, machine tool slides, jigs, fixtures, and other industrial mechanisms where controlled axial movement is required. The machinable designation indicates that bore or flange modifications can be performed to fit custom housings or mounting configurations. It is appropriate for light to moderate duty applications in both OEM machine builds and MRO replacement scenarios. The right-hand thread direction is standard for most power screw assemblies in industrial and mechanical trade environments.

Key Features

• 1/2-10 right-hand Acme thread with single thread start for reliable linear positioning
• 2C class of fit for controlled clearance and smooth engagement with mating Acme screws
• Gray iron construction provides good wear resistance and machinability for secondary operations
• 1 inch overall height suits compact linear mechanism designs
• Overall diameter of 1.465 inches in a round form factor for easy mounting or further machining
• Manufactured to ISO 9001:2019 quality management standards

Compatibility

Designed as a replacement or OEM-style Acme nut for power screw and lead screw assemblies using a 1/2-10 right-hand Acme thread with a 2C class of fit.

Installation Notes

Installation is typically performed by machinists or mechanical maintenance technicians. Before installation or replacement, de-energize all connected drive systems and relieve any load on the lead screw assembly. Inspect the mating Acme screw threads for wear or damage before installing a new nut, as a worn screw will accelerate nut wear. If secondary machining is performed, confirm dimensional tolerances against the assembly drawing before final fitment.
