• Coarse thread configuration enables faster assembly and reduced cross-threading risks in production environments

Professional Applications & Engineering Value

This M12 nylon insert flange lock nut delivers critical vibration resistance for machinery, automotive, and industrial equipment where secure fastening under dynamic loads is essential. The combination of Class 10 strength steel and precision nylon insert locking mechanism prevents loosening caused by equipment vibration, thermal cycling, and operational stresses. The integrated 26mm flange distributes clamping force over a wider area, reducing surface pressure and preventing damage to connected components. With zinc yellow-chromate plating, these nuts maintain integrity in corrosive environments while the metric coarse thread (M12 x 1.75) ensures quick, reliable installation in high-volume assembly operations. Engineered to DIN 6926 standards, these flange lock nuts provide consistent performance in automotive subsystems, industrial machinery, and construction equipment where vibration-induced failure is a primary concern.

Specification Summary & Compliance
