Professional Applications & Engineering Value
This Acetal Plastic flange nut is engineered for ultra-precision lead screw systems where minimal friction, chemical resistance, and exact positioning are critical. The rounded Acme thread profile reduces wear and provides smooth motion transfer, making it ideal for laboratory equipment, medical devices, and optical positioning systems that demand 0.048" travel per turn accuracy. Its flange design with pre-drilled mounting holes simplifies installation while maintaining alignment stability, addressing common challenges of vibration and misalignment in precision motion control applications. The Acetal material ensures consistent performance without lubrication, even in environments exposed to mild chemicals or moisture.
Specification Summary & Compliance
This flange nut features a 9/64"-20.8 rounded Acme thread with right-hand direction and single start configuration. Critical dimensions include 1/2" length, 0.406" diameter, and flange dimensions of 3/4" width with 39/64" mounting hole spacing. The component meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental safety for industrial integration. Manufacturing follows precision thread forming standards suitable for ultra-precision lead screw assemblies requiring exact travel control.
