Hex Flange Nuts (Serrated)
Hex flange nuts have an integrated flange that spreads the clamping load over a wider area, so no separate washer is needed. The serrated (toothed) version has teeth on the bearing face that bite into the mating surface and resist loosening under vibration — a simple, reliable alternative to a nylon insert lock nut where a low profile is required.

Frequently Asked Questions
How do serrated flange nuts resist loosening?
The serrations on the flange underside bite into the mating surface when tightened, dramatically increasing resistance to rotation under vibration — while the flange itself spreads the load like a built-in washer.
