Fasteners used in lightning protection should be ...

The use of fasteners made from a compatible material with the cable in use is critical for ensuring the integrity and effectiveness of the lightning protection system. Lightning protection systems rely heavily on the conductivity and structural stability of the components used in the system. Using materials that are compatible helps to prevent galvanic corrosion, which can occur when dissimilar metals are in contact in the presence of moisture, ultimately degrading the performance of the system over time.

Compatible materials often refer to those that share similar electrical and mechanical properties, allowing for secure connections that can handle the immense electrical currents generated during a lightning strike. This compatibility ensures that the fasteners do not interfere with the conductivity of the lightning protection system, maintaining the necessary path for lightning energy to flow into the ground safely.

Other materials or coatings, such as plastic coatings or specific types of metal, could impair electrical continuity or create potential failure points in the system. Thus, selecting fasteners based on compatibility with the main materials being used is essential for safety and functionality.
