Flange Nut

Flange Nuts

(Integrated Washer Design for Vibration Resistance and Even Load Distribution)

Neo Fasteners offers a wide range of Flange Nuts, engineered with an integrated flared base (flange) that provides a built-in washer function. This design ensures greater surface area contact, prevents loosening under vibration, and distributes the load more evenly over the fastening surface—making them ideal for automotive, machinery, and structural applications.

Whether you need standard, serrated, or self-locking flange nuts, we provide precision-grade fasteners to meet your industry’s specific requirements.

🔩 Product Overview:

Flange Nuts are hex nuts with a wide flange at one end that acts as a non-spinning washer. This design eliminates the need for a separate washer, reduces surface damage, and improves resistance to vibration loosening. Serrated flange nuts further enhance grip by digging into the surface material to prevent back-off in high-vibration conditions.

They’re widely used in automotive assemblies, industrial machinery, metal fabrication, and structural steelwork.
