Professional Applications & Engineering Value

This zinc-plated steel flange nut delivers critical engineering advantages where vibration resistance and load distribution are paramount. The 16mm flange diameter significantly increases bearing surface area, preventing joint loosening in automotive assemblies and machinery applications subjected to dynamic stresses. The M6x1mm coarse thread with Class 6G fit maintains precise tolerances while accommodating minor material variations, ensuring reliable performance in high-volume manufacturing. The zinc plating provides sacrificial protection against corrosion, making these metric flange nuts suitable for outdoor equipment and industrial environments where moisture exposure is common. This combination of features addresses common fastener failure points while streamlining assembly processes.

Specification Summary & Compliance

Manufactured to metric standards with M6x1mm coarse right-hand threads meeting Class 6G thread fit tolerances for consistent engagement. Features a 10mm hex drive, 16mm flange diameter, and 8mm height. Compliant with RoHS 3 (2015/863/EU) with exemption 6(a)-I and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial fastener applications.
