Frequently Asked Questions
What is the difference between a flange bolt and a regular hex bolt?
A flange bolt has a built-in circular flange under the head that acts as an integrated washer, distributing the clamping load over a wider surface area. A standard hex bolt requires a separate flat washer to achieve the same effect. Flange bolts are faster to install, reduce the risk of missing washers during assembly, and provide better vibration resistance.
What is the difference between serrated and non-serrated flange bolts?
Serrated flange bolts have small teeth or ridges on the underside of the flange that dig into the mating material, providing a locking action similar to a spring washer. They are ideal for high-vibration applications. Non-serrated (smooth) flange bolts have a plain flange and are used where a clean, unmarked surface contact is important or where the mating surface is soft or coated.
