2. Corrosion Resistance Many hex head bolts come with protective coatings, such as zinc plating or galvanization, which enhance their resistance to corrosion. This feature is particularly important in outdoor or marine environments, where exposure to moisture and harsh conditions can lead to rapid deterioration.

The body of a hex head bolt features external threads that engage with a corresponding nut or a tapped hole, allowing for a secure and adjustable connection. Depending on the intended application, these bolts can be made from various materials, including steel, stainless steel, and even plastic, each offering different levels of strength, corrosion resistance, and weight considerations.
