Professional Applications & Engineering Value

This 1/4-12 ACME lead screw nut is engineered for fast-travel precision applications where speed and reliability are critical. The PET plastic material reduces weight and provides inherent lubrication, minimizing the need for external lubricants and reducing maintenance in environments like packaging, automation, and CNC positioning systems. Its 4-start Acme thread and 4:1 speed ratio enable rapid linear displacement, solving common bottlenecks in high-cycle operations. The Class 2C thread fit ensures consistent performance with minimal play, enhancing positional accuracy in industrial plastic nut assemblies. Ideal for use in right-hand thread configurations, it supports dynamic loads up to 160 lbs, making it a robust choice for thrust-loaded mechanisms.

Specification Summary & Compliance

This nut features a 1/4"-12 Acme thread with Class 2C fit for precise tolerance and smooth operation. It is manufactured from PET plastic and operates within a temperature range of 15° to 175° F. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring adherence to environmental and safety regulations for industrial components.
