Professional Applications & Engineering Value

This Acetal Plastic Flange Nut is engineered for fast-travel lead screw systems where speed, precision, and durability are critical. The rounded Acme thread and right-hand thread direction ensure smooth, efficient motion transfer with minimal backlash. Its wear-compensating spring addresses common issues of thread degradation in high-cycle applications, maintaining positional accuracy over the long term. The acetal material is inherently resistant to many chemicals and moisture, preventing corrosion and reducing maintenance needs. This makes it an excellent choice for industrial automation, packaging equipment, medical devices, and 3D printers, where reliable, high-speed linear motion is essential for operational efficiency and product quality.

Specification Summary & Compliance

This flange nut features a 1/2"-8 rounded Acme thread with standard thread form tolerances. It is manufactured from high-grade acetal plastic and includes a flange with a 1 1/4" bolt circle diameter and three 13/64" mounting holes for secure attachment. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets the latest environmental and safety standards for industrial components.
