Professional Applications & Engineering Value

This extra long coupling nut solves critical spacing challenges in industrial assemblies where standard fasteners cannot reach. The 18-8 stainless steel construction delivers exceptional corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or outdoor elements. The 1/2"-20 UNF fine threading with Class 2B thread fit ensures precise engagement in machinery, structural frameworks, and mechanical linkages where vibration resistance is paramount. The 5" length enables connections through barriers or between widely spaced components, while the external hex drive allows for high-torque installation without compromising the nut's integrity. This coupling nut is particularly valuable in manufacturing equipment, transportation systems, and construction applications requiring durable, long-lasting threaded connections.

Specification Summary & Compliance

This coupling nut features 1/2"-20 UNF fine threading with Class 2B thread fit per UNF standards, ensuring precise dimensional accuracy and reliable performance. The partially threaded design provides optimal engagement while the right-hand thread direction follows conventional installation practices. Manufactured from 18-8 stainless steel with external hex drive configuration, this extra long coupling nut measures 3/4" in width and 5" in length with a minimum thread length of 3/4". The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest substance restriction requirements for industrial applications.
