Rivets are used to replace traditional nut and bolt or welding applications. This is because rivet fasteners improve speed and efficiency for nearly all assembly processes. There are a variety of types of rivets that may be used depending on the application, including blind, drive, expanding, bulbing, solid, structural, non-structural, semi-tubular, mate, military specification, pull-thru, and other specialty rivets. Additionally, there are nylon rivets available, along with an assortment of alloys, plastics and more. For finishes, rivets may be painted, plated or coated in protective oils.
