Flange nuts are specialized hex nuts with a wide washer-like flange at the base, designed to distribute pressure evenly over the clamped surface. This design eliminates the need for a separate washer and helps reduce loosening caused by vibration. Our flange nuts are available in both serrated and non-serrated styles, meeting a wide range of structural and mechanical fastening requirements.
With precise thread profiles and consistent dimensions, our factory supplies full-size ranges including M6, M8, M10, M12, M14, M16, and M20 flange nuts, fully compliant with international standards such as DIN 6923, ISO 4161, and JIS B1190.
