Hex Flange Nuts

Serrated flange hex nuts are designed with a wide built-in flange that helps distribute clamping force across a larger surface area. This integrated flange acts like a non-spinning washer, helping reduce damage to the installation material while supporting a more secure fit on compatible bolts.

The serrated bottom surface provides added locking action during installation, helping the nut resist loosening in applications where vibration or movement may occur. These flange nuts are a practical choice when both load distribution and improved holding power are important.
