Professional Applications & Engineering Value
This extra long coupling nut solves critical spacing challenges in industrial assembly where standard nuts cannot bridge the required distance. The 18-8 stainless steel material provides exceptional corrosion resistance for applications in chemical processing, marine environments, and outdoor installations where moisture exposure is a concern. The Class 6H thread accuracy ensures precise alignment and secure fastening in mechanical linkages, hydraulic systems, and structural frameworks. The partial threading allows engineers to fine-tune the position while the coarse metric thread pitch facilitates rapid assembly in production environments. This M20 coupling nut delivers reliable performance in conveyor systems, machinery frames, and construction applications where vibration resistance and long-term durability are essential.
Specification Summary & Compliance
This metric coupling nut features M20x2.5 coarse threading with Class 6H thread fit per ISO standards, ensuring precise dimensional accuracy and reliable performance. The nut measures 120mm in length with a 30mm width across flats and provides a minimum thread length of 20mm. Manufacturing complies with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, confirming environmental compliance and safety for industrial applications worldwide.
