Professional Applications & Engineering Value

Engineered for ultra-precision lead screw assemblies, this Acetal Plastic flange nut solves critical challenges in motion control systems where precision, weight, and chemical resistance are paramount. The rounded Acme thread form minimizes wear particles while maintaining precise engagement with mating screws, eliminating the need for frequent maintenance in sensitive environments like medical devices, optical positioning systems, and laboratory automation. With 0.024" travel distance per turn, it delivers micron-level positioning repeatability, while the integrated flange with mounting holes eliminates alignment issues common in separate nut and bracket configurations. The Acetal material provides inherent lubrication properties that reduce the need for external lubricants in cleanroom applications, making it ideal for industries where contamination control is critical.

Specification Summary & Compliance

This 9/64"-41.7 flange nut features inch system measurements with precision rounded Acme threads and right-hand thread direction.
