Flange Nut, Serrated

Serrated flange nuts are hex nuts with built-in non-spinning washers with serrations on the bottom. This kind of flange nut is used to help prevent loosening when vibrations are present. Hex flange nuts are very common and used widely in softer installation materials. These nuts come with a serrated flange. These flange nuts come with serrations on the flange's bottom to create a locking effect. The serrations bite into the material installed, making the nut less likely to loosen over time due to vibrations. Hex flange nuts also save time and money by removing the need for a washer added to each fastener assembly during installation.
