Keystone Threaded Products NQ008AC1A001965 Precision Acme Nut

Product Description

The KEYSTONE THREADED PRODUCTS NQ008AC1A001965 is a round precision Acme nut machined from bronze, designed for use in linear motion, power transmission, and positioning applications. It features a 1/2-10 Acme thread with a right-hand thread direction and a 2C class of fit, which is suitable for general-purpose power screw assemblies where controlled clearance is required. Overall length is 1.12 inches, height is 0.75 inches, and thread engagement length is 0.5 inches. This part is manufactured to ISO 9001:2019 standards. It is typically installed by mechanical assemblers, machine builders, or maintenance technicians working with lead screw or Acme screw drive systems.

This precision Acme nut is suited for industrial machinery, automated equipment, actuators, and mechanical assemblies that rely on Acme-thread lead screws for controlled linear travel. The single-start thread profile provides predictable mechanical advantage and is commonly found in both OEM manufacturing and aftermarket replacement scenarios. Its bronze construction offers natural lubricity and wear resistance, making it a practical choice for moderate-load, moderate-speed screw drive assemblies in both production and field-service environments.

Key Features

• 1/2-10 Acme thread with single thread start for reliable linear drive performance
• 2C class of fit provides controlled clearance suitable for general power-screw applications
• Bronze material offers inherent lubricity and resistance to wear against steel lead screws
• Right-hand thread direction for standard-orientation Acme screw assemblies
• Round external profile at 1.12 inches overall diameter for straightforward housing or flange mounting
• Manufactured under ISO 9001:2019 quality management standards

Compatibility

Designed for use with standard 1/2-10 Acme lead screws in linear motion and power transmission assemblies requiring a 2C class of fit bronze nut.

Installation Notes

Installation is typically performed by mechanical assemblers or maintenance technicians familiar with lead screw drive systems. Ensure the mating Acme screw is clean, free of burrs, and properly aligned before threading the nut into position. Disengage and lock out all power to any driven equipment before replacing or servicing lead screw components. Do not force-thread the nut onto the lead screw, as improper engagement can damage the thread form and alter the class of fit.
