Leader-Fastener® ANSI B18.2.4.4M Hex flange nuts are very common and used widely in softer installation materials. These nuts come with either a serrated or non-serrated flange. The non-serrated flange gives some of the benefits of a standard flat washer. The serrated version of a flange nut comes 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.
