Across aviation, defense, and space programs, the mechanical integrity of any assembled structure hinges on the use of seemingly simple components known as fasteners, which are rarely visible or outwardly noticeable once work is complete. While not always appearing to be as important as major wing structures, onboard electronics, or flight controls, aerospace fasteners are essential for countless workpieces to remain securely together in the face of great operational and environmental stress. As such, procurement professionals and maintenance teams working across aerospace and aviation industries can gain much benefit from understanding the importance of aerospace fasteners and how their selection is governed. For this, we invite you to read on for a clear overview of aerospace fasteners, our blog covering topics ranging from the characteristics that define the broad category of items to the way these components are organized by type and specification.
