Bolts
Bolts are fastening elements consisting of a cylindrical rod with an external thread and a head of various shapes, designed for connecting and securing different components of pipelines, equipment, and structures. They create a strong connection capable of withstanding significant mechanical loads and vibrations. Bolted joints allow for easy maintenance, assembly, and disassembly of various systems without damaging the connected elements.
