70MM Counter Sunk Self Drilling Screw

The CSK Head Self-Drilling Screw is a specialized fastener designed for efficient and secure joining of materials, particularly in construction and metalworking applications. Its key features include: CSK Head (Countersunk Head): The flat, conical head allows the screw to sit flush with or below the surface of the material, providing a smooth finish. Self-Drilling Tip: Equipped with a drill point, the screw can create its own pilot hole, eliminating the need for pre-drilling and saving time and effort. Thread Design: The threads are optimized for strong grip and resistance to loosening, ensuring a durable connection. Material: Typically made from high-strength steel, often with coatings like zinc or stainless steel for corrosion resistance. Applications: Widely used in metal-to-metal or metal-to-wood fastening, such as in roofing, cladding, and framing. Advantages: Combines drilling and fastening in one step, reduces labor costs, and ensures a secure, long-lasting hold.…
