What is the difference between flange nuts and hexagonal nuts?

1. Appearance structure
Flange nuts have larger flanges, while hexagonal nuts have a standard regular hexagonal shape.
2. Contact surface
The flange of flange nuts increases the contact area with the connected parts, while the contact area of ​​hexagonal nuts is relatively small.
3. Fastening effect
Flange nuts usually provide better fastening stability and anti-loosening performance, while hexagonal nuts are relatively weak in this regard.
4. Pressure distribution
Flange nuts can disperse pressure more evenly and reduce damage to the surface of the connecting parts; the pressure distribution of hexagonal nuts is relatively concentrated.
5. Use of washers
In many cases, flange nuts do not require additional washers, while hexagonal nuts sometimes need to be used with washers.
6. Application scenarios
Flange nuts are often used in situations where stability requirements are high and pressure dispersion is required; hexagonal nuts are widely used and are more common in general fastening connections.
7. Installation convenience
The flange of flange nuts may be easier to operate and position during installation.
