Fasteners are mechanical components used to hold two or more parts together, fix them, or join them in a way that allows them to be disassembled when necessary. Products such as bolts, nuts, screws, washers, and studs play a critical role in many sectors, especially construction, machinery, automotive, energy, and heavy industry. The choice of the right fastener in industrial applications is of vital importance for system safety. An incorrectly chosen bolt can cause serious failures and costly downtime due to loosening, breaking, or corrosion. Especially in vibrating environments, high temperatures, or applications with chemical contact, the material and coating selection of the fastener must be made carefully. Fasteners are generally classified as removable (bolt-nut) and permanent (rivets, etc.). Bolted connections are the most preferred method due to ease of maintenance and assembly. In these systems, the load is carried through the bolt body and threads.
