Keystone Threaded Products NQ016AC1A003865 Acme Nut

Product Description

The KEYSTONE THREADED PRODUCTS NQ016AC1A003865 is a round, precision Acme nut machined from bronze, designed for use in linear motion systems, lead screw assemblies, and power transmission applications. It features a 1 inch diameter, 10 TPI Acme thread with a right-hand thread direction and a 2C class of fit, making it suitable for applications that require controlled clearance and reliable axial load transfer. The bronze material provides natural lubricity and corrosion resistance, reducing maintenance requirements in demanding service environments. This nut is sold individually and is appropriate for installation by mechanical, industrial, and trade professionals working on actuator or drive systems.

This precision Acme nut is used in residential and commercial mechanical assemblies where a lead screw or Acme-threaded rod converts rotary motion into linear movement. Common install scenarios include valve actuators, positioning stages, and HVAC damper drive mechanisms. The 2C thread fit class allows for smooth engagement with mating Acme screws while maintaining adequate load capacity. The round outer profile facilitates installation into bored housings or flanged mounts depending on the application design.

Key Features

• 1 inch diameter, 10 TPI Acme thread with right-hand thread direction
• 2C class of fit for controlled clearance in lead screw assemblies
• Bronze material provides inherent lubricity and corrosion resistance
• Round outer form suits bored housing and flange-mount configurations
• Single-start thread design for predictable linear travel per revolution
• Manufactured to ISO 9001:2019 quality standards

Compatibility

Designed as a precision replacement or new-installation Acme nut for lead screw assemblies using 1 inch, 10 TPI Acme-threaded rods with a 2C class of fit.

Installation Notes

Installation is typically performed by mechanical or industrial technicians familiar with lead screw and linear actuator systems. Disengage and de-energize the drive system completely before removing or replacing any threaded components. Verify that the mating Acme screw thread profile and fit class match this nut before assembly to prevent galling or excessive play. Do not over-torque the nut into its housing; follow the equipment manufacturer's assembly specifications for preload and retention.
