4. Variety of Heads and Coatings Tek screws come in various types of heads (such as hex, pan, or round) and can be coated in materials like zinc or epoxy for increased resistance to rust and corrosion. This allows for customization based on the specific needs of a project.
The process of galvanization involves coating the steel screw with a layer of zinc to protect it from rust and deterioration. This makes self-drilling galvanized screws particularly suited for applications in construction, roofing, and outdoor furniture, where exposure to moisture and other environmental conditions is prevalent.
