Keystone Threaded Products NQ010AC1A002560 Precision Acme Nut

Product Description

The KEYSTONE THREADED PRODUCTS NQ010AC1A002560 is a round precision acme nut machined from bronze for use in linear motion and power transmission assemblies. It features a 5/8 inch - 8 acme thread profile with a right-hand thread direction and a 2C class of fit, providing controlled clearance suitable for general-purpose power screw applications. At 1.12 inches in overall length and 1 inch in height, this compact nut is sized for use in lead screw mechanisms, actuators, and positioning equipment across industrial, HVAC, and mechanical systems. Installation is performed by qualified mechanical or maintenance technicians.

This acme nut is suited for residential and commercial mechanical assemblies where a lead screw or power transmission screw requires a durable, low-friction nut. Bronze construction provides natural lubricity and corrosion resistance, making it appropriate for applications in valve actuators, damper drives, and linear positioning stages. The single-start thread and 2C fit class are standard for general-purpose acme drive systems where moderate backlash is acceptable. The part ships in a quantity of one per package with a minimum order quantity of one.

Compatibility

Designed as an OEM-style replacement or component-level fit for lead screw and power transmission assemblies using a 5/8 inch - 8 acme thread with a 2C class of fit and right-hand thread direction.

Installation Notes

Installation is typically performed by a licensed mechanic or qualified maintenance technician. Disengage and lock out all power to the actuator or drive assembly before removing the existing nut or installing this component. Ensure the mating lead screw is free of burrs, debris, and excessive wear before threading on the new nut. Do not force the nut onto a screw that does not turn freely by hand, as this indicates misalignment or thread damage.
