- Reduced system weight and noise compared to metal alternatives while maintaining dimensional stability
- Simplified installation with integrated flange featuring two 1/8" mounting holes at 39/64" centers
- Smooth, efficient operation thanks to rounded Acme thread profile that minimizes friction and wear
- Reliable performance with 25 lbs dynamic thrust capacity for light to moderate load applications
- Global compliance ready meeting both RoHS 3 and REACH environmental standards for international projects
Professional Applications & Engineering Value
This Acetal Plastic flange nut with 7/32"-20.8 Rounded Acme threads delivers exceptional value in ultra-precision positioning systems where metal components would introduce corrosion, weight, or electrical conductivity concerns. The rounded Acme thread form provides smoother engagement and reduced wear compared to standard Acme threads, while the integrated flange with mounting holes eliminates the need for separate mounting hardware. Engineered for medical devices, laboratory automation, and precision instrumentation, this nut solves critical challenges in applications requiring consistent 0.048" travel per turn with minimal backlash and maintenance-free operation in demanding environments.
Specification Summary & Compliance
This flange nut features precision 7/32"-20.8 Rounded Acme threads with right-hand direction and single start configuration. Critical dimensions include 0.406" diameter, 1/2" length, and flange dimensions of 3/4" width × 13/32" height × 1/8" thickness. The component maintains standard inch system tolerances suitable for ultra-precision lead screw assemblies and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for global deployment.
