What type of sheet metal screws can electricians use for bonding purposes?

Red screws with flat heads

Green screws with hexagonal heads

Electricians use green screws with hexagonal heads for bonding purposes because they are specifically designated for grounding and bonding electrical systems. The green color provides a visual identifier that indicates the screw is intended for this purpose, ensuring that any person working on electrical systems can quickly recognize the appropriate hardware for grounding applications. This minimizes the risk of incorrect installations and helps maintain safety standards as outlined by the National Electrical Code (NEC). The hexagonal head design also allows for easier installation with a wrench and provides a reliable grip during application, further enhancing the effectiveness of the electrical bond.
