Hot-Forged Nuts - High-Strength Fastening Solutions
A flange nut is a specialized fastening component designed with an integrated wide flange at one end, which acts like a built-in washer. This structure distributes pressure evenly across the joint surface, reduces material deformation, and improves resistance against loosening caused by vibration. Flange nuts are widely used in automotive, heavy machinery, wind energy, petrochemical, and marine engineering, where secure fastening and long-term reliability are critical.
Types and Features
Serrated Flange Nuts – The serrated surface “bites” into the material surface, providing strong resistance to loosening under vibration.
Self-Aligning Flange Nuts – Designed with spherical features or paired with matching washers to allow use where the nut face is not perfectly perpendicular, ensuring even load distribution.
Standard / Locking Variants – Manufactured in compliance with standards such as ISO 4161, DIN 6923, and ASME B18.2.2, ensuring compatibility and performance consistency.
