Professional Applications & Engineering Value

This M12 flange nut delivers critical engineering solutions where vibration resistance and surface protection are paramount. The zinc-plated steel construction combined with the 26 mm flange diameter creates an integrated washer function that distributes clamping force over a wider area, preventing damage to softer materials and reducing the risk of loosening under dynamic loads. The fine 1.25 mm thread pitch provides more thread engagement points compared to coarse threads, significantly enhancing resistance to vibrational loosening in machinery, automotive assemblies, and structural applications. Manufactured to DIN 6923 and ISO 4161 standards, this Class 8 strength fastener ensures reliable performance in high-stress environments while the external hex drive design maintains compatibility with standard installation tools for efficient assembly operations.

Specification Summary & Compliance

This precision metric flange nut features M12x1.25 fine right-hand threads with Class 6H thread fit tolerance for consistent engagement. The 18 mm width across flats and 12 mm height provide standard dimensional compatibility, while the 5.3 mm flange thickness ensures structural integrity. Manufactured in compliance with DIN 6923 and ISO 4161 specifications, this component meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives, confirming its suitability for regulated industrial applications worldwide.
