Studs and other fasteners are crucial in any application to ensure that important pieces and components are held together during operation. In the high-stakes aerospace, aviation, and defense industries, where fasteners are subject to extreme conditions at high altitudes, they are that much more important. Before looking at studs, it’s important to understand fasteners as a whole. All studs are fasteners, but not all fasteners are studs. In addition to studs, fasteners refer to bolts, screws, nuts, and rivets. The singular purpose of fasteners is to join parts together. Fasteners are not intended to position aircraft parts relative to another, or to operate similarly to axles, pivots, or fulcrums.
