Professional Applications & Engineering Value

Engineered to solve critical vibration-induced loosening problems in industrial equipment, these M5 flange lock nuts combine nylon insert technology with Class 8 strength for permanent fastening solutions. The integrated flange design eliminates the need for separate washers while providing superior load distribution on connected surfaces. Made from black corrosion-resistant coated steel, these nuts maintain integrity in moist or chemically aggressive environments common in automotive assembly, machinery manufacturing, and electrical enclosures. The coarse metric threading (0.8mm pitch) ensures quick installation and reliable performance in high-vibration applications where fine threads might fail.

Specification Summary & Compliance

This M5 x 0.8mm flange lock nut features Class 6H thread fit per ISO metric standards with coarse thread spacing and right-hand direction. Manufactured to DIN 6926 specifications with standard hex profile (8mm width, 7.1mm height) and 11.8mm flange diameter. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across industrial sectors.
