A flange bolt differs from a common bolt in that it has a larger surface area under the head to provide more bearing surface. This wider surface acts much like a washer, eliminating the need to use a washer with this kind of bolt. Specially designed flange bolts can be equipped with anti-rotational teeth designed to bite or dig into the material being fastened to. These may appear similar to the locking rings one might see on a soda bottle or milk jug. Yet these teeth on the flange bolt can be turned backward, but often require more force and may damage a surface softer than the flange bolt. Designed to hold connections tightly without slippage or loosening, flange bolts are standard in most industrial applications where secure connections are crucial.

In an application where long term installations under harsh conditions are common, using a flange bolt made of steel that will inevitably rust and corrode can be an expensive and time consuming mistake. Titanium flange bolts are not only corrosion proof in the natural environment, but they also weigh nearly half as much as their stainless steel counterparts. Known primarily for its amazing strength-to-weight ratio, titanium is not only lighter and corrosion free, but it is also stronger. A grade 5 (6Al-4V) titanium flange bolt is approximately 3 and a half times stronger than one made of high quality 316 stainless steel, making it the ideal choice of fastener when strength is an issue.

Using titanium also allows for re-engineering in some applications, where material needs to be reduced without losing structural integrity. Replacing steel flange bolts with titanium ones will inevitably lengthen the life of the product/structure by never needing to be replaced due to corrosion.
