Keystone NQ016AMAA003865 Precision Acme Nut Bronze

Product Description

The KEYSTONE THREADED PRODUCTS NQ016AMAA003865 is a round, bronze precision acme nut designed for high-accuracy linear motion and power transmission applications. It features a 1.375-16 thread size with a 2C class of fit, 10 thread starts, and a right-hand thread direction. The nut measures 1.5 inches in overall length and 1.5 inches in height, with a thread engagement length of 0.5 inches. Weighing 0.554 pounds, this nut is machined from bronze, offering natural lubricity, corrosion resistance, and low friction under load. It is suited for use in lead screw assemblies, positioning systems, and mechanical drive mechanisms encountered in HVAC, industrial, and mechanical service environments.

This precision acme nut is used in applications where accurate, repeatable linear motion is required. Typical installations include lead screw drives in damper actuators, valve positioners, and mechanical lifting or positioning assemblies. The 2C class of fit provides a controlled amount of backlash suitable for general-purpose power transmission rather than zero-backlash precision positioning. Licensed mechanical technicians and machine maintenance professionals are the primary installers of this component in both commercial and industrial settings.

Key Features

• 1.375-16 thread size with 2C class of fit for controlled backlash in power transmission
• 10 thread starts for fast linear advancement per revolution
• Bronze material provides self-lubricating properties and corrosion resistance
• Right-hand thread direction for standard mechanical drive assemblies
• Round body profile at 1.5 inches overall diameter for easy installation and alignment
• Thread length of 0.5 inches optimized for compact lead screw engagement

Compatibility

Designed as an OEM-style replacement or direct-fit component for precision acme lead screw assemblies requiring a 1.375-16 thread size with a 2C class of fit and right-hand thread direction.

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with lead screw and power transmission assemblies. De-energize and lock out all mechanical and electrical power to the system before removing or installing this nut. Ensure mating lead screw threads are free of debris and in serviceable condition before assembly. Do not force-thread the nut onto a damaged or misaligned screw, as this may damage the precision thread profile.
