Professional Applications & Engineering Value

This 3/8-12 Acetal Plastic Flange Nut is engineered specifically for fast-travel ultra-precision lead screw systems where speed and accuracy are critical. The rounded Acme thread profile with three thread starts creates multiple load-bearing surfaces that distribute stress evenly, minimizing wear and extending service life. The Acetal plastic material offers natural lubricity that reduces friction-induced heat buildup and eliminates the need for external lubricants in sensitive environments. This combination makes the nut ideal for high-speed automation equipment, precision positioning systems, and medical device applications where clean, maintenance-free operation is essential. The right-hand thread direction ensures compatibility with standard drive systems while the integrated flange design provides stable mounting for vibration-resistant performance.

Specification Summary & Compliance

This precision component features a 3/8"-12 rounded Acme thread with standard inch measurements including 1" length and 0.625" diameter. The flange measures 1-7/64" diameter with 3/16" thickness and includes three 9/64" mounting holes on a 7/8" bolt circle. The nut delivers 75 lbs dynamic thrust load capacity and 9700 psi tensile strength. Manufactured to precision engineering standards, this component is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting the latest environmental regulations for industrial components.
