Professional Applications & Engineering Value
This M18 cap nut is engineered to address critical challenges in industrial assembly, where corrosion resistance and mechanical reliability are paramount. Manufactured from 18-8 stainless steel, it effectively combats rust and degradation in moist or chemically aggressive settings, reducing maintenance costs and downtime. The coarse metric thread (M18 x 2.5 mm) and Class 6H thread fit deliver superior clamping force and are less prone to cross-threading, speeding up installation in high-volume production lines. With an external hex drive and compliance with DIN 1587, it ensures consistent performance in machinery, structural frameworks, and automotive systems, providing a dependable sealing solution that protects internal threads from contaminants and damage.
Specification Summary & Compliance
This metric cap nut adheres to precise dimensional standards, including a Class 6H thread fit per ISO metric specifications, M18 thread size with a 2.5 mm coarse pitch, and compliance with DIN 1587 for manufacturing consistency. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances. Key dimensions are 27 mm width, 32 mm height, and 24.6 mm thread depth, supporting reliable use in industrial fastening applications.
