3. Environmental Factors The choice of materials for self-drilling bolts, such as coatings or finishes, should consider the environmental conditions they will face, including exposure to moisture or corrosive substances.

Self-drilling screws, often referred to as Tek screws, are equipped with a drill bit-like tip that enables them to drill through metal and other hard materials. These screws are typically made from high-strength materials such as carbon steel or stainless steel, which grant them exceptional durability and resistance to corrosion. Self-drilling screws come in various sizes and lengths, suitable for different applications, from roofing and siding to metal framing and vehicle construction.
