Professional Applications & Engineering Value

This 3/8"-32 coupling nut delivers critical engineering value in applications requiring fine-adjustment capabilities and robust threading. Manufactured from 18-8 stainless steel, it resists corrosion in industrial settings like chemical processing, marine hardware, and precision machinery. The UNEF extra fine thread provides more threads per inch, enhancing grip and load distribution in thin-walled components or where vibration loosening is a concern. Its fully threaded, standard profile ensures uniform stress transfer, making it a dependable solution for extending threaded rods, aligning shafts, or joining components in tight spaces. By complying with ASTM A582, it guarantees material integrity and performance consistency for B2B procurement in OEM and MRO sectors.

Specification Summary & Compliance

This coupling nut adheres to Class 2B thread fit and UNEF (Extra Fine) thread standards with a size of 3/8"-32 and right-hand direction. It meets ASTM A582 specifications for material and manufacturing, ensuring dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility in global supply chains.
