Professional Applications & Engineering Value
This M2.5 coupling nut manufactured from Nylon 6/6 plastic delivers critical engineering solutions where metal fasteners fall short. The coarse metric threading with Class 6H precision provides excellent vibration resistance while the fully threaded design maximizes connection strength between components. Ideal for electrical insulation applications, chemical processing equipment, and weight-sensitive assemblies, this external hex coupling nut offers non-conductive properties and corrosion resistance that metal alternatives cannot match. The high-temperature capability ensures reliability in automotive, aerospace, and industrial machinery where thermal cycling is common, while the right-hand thread direction maintains compatibility with standard installation practices.
Specification Summary & Compliance
This metric coupling nut features M2.5 coarse threading with Class 6H thread fit per ISO standards, measuring 4.5mm width across flats and 6mm length. The Nylon 6/6 material provides consistent performance within the specified temperature range of -40°F to 250°F. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory compliance for industrial applications worldwide.
