Flange bolts have a standard hex head with a ‘flange’ beneath which extends out acting as an attached washer to the threaded bolt. This design feature allows the flange bolt to distribute more weight when being tightened, further increasing the strength of the connection. Fasteners Etc. Inc. offers flange bolts with and without serrations on the underside of the flange. We can offer a great selection of standard flange bolts in grade 5 and grade 8 as well as metric flange bolts in class 8.8 and class 10.9, multiple finishes as well. Don't forget to add nuts to your cart to complete the project! If you don’t see the size or thread requirements you need, please feel free to send us a request for quote!
