Flange Nut

This flange nut integrates a standard hexagonal nut body and an enlarged circular flange with anti-slip serrated teeth on the contact surface. The integrated flange replaces separate flat washers, simplifying assembly procedures while providing excellent anti-loosening performance under vibration conditions.

It is made of high-quality carbon steel and treated with blue white zinc plating on the surface to form a dense anti-rust protective layer, effectively resisting oxidation and corrosion in general indoor and semi-outdoor environments. The serrated texture on the flange surface bites tightly into the workpiece surface during tightening, preventing the nut from rotating and loosening caused by long-term mechanical vibration.

The six-sided outer hexagon matches standard spanners and sockets for convenient torque control. Precisely rolled internal threads fit metric bolts perfectly, delivering stable and uniform clamping force. The one-piece integrated structure saves assembly time and reduces the number of spare parts required for production lines.

Flange nuts are widely used in automobile assembly, motorcycle accessories, home appliance shell fixing, general mechanical equipment and engineering metal frames. It is an all-in-one fastener ideal for assemblies that need anti-vibration and simplified installation.

We provide full customized service, including adjustable thread specifications, flange width and tooth depth. Laser marking brand logos can be printed on the nut surface to support brand sales for hardware distributors and auto parts manufacturers.

All finished flange nuts pass complete quality tests before delivery, including dimension inspection, thread precision test, serration anti-slip test and plating appearance inspection, to ensure stable thread fit, reliable anti-loosening performance and consistent anti-corrosion finish for every batch.
