Frequently Asked Questions (FAQ)
What are the main advantages of using a flange nut?
Flange nuts feature a built-in circular flange that acts as an integrated washer. This design distributes clamping pressure over a larger surface area, preventing damage to the mating material and eliminating the need for a separate washer.
How does a serrated flange nut prevent loosening?
The serrations on the underside of the flange bite into the surface of the material when tightened. This provides high resistance to vibration-induced loosening, making them ideal for high-vibration applications like automotive and machinery assemblies.
