butterfly anchor screws

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.

Moreover, the robustness of stainless steel self-drilling screws extends to their load-bearing capacity. Their strong threads provide excellent holding power, ensuring a secure and stable connection between the joined materials. They are also resistant to shearing and tensile forces, thus maintaining their integrity even under heavy loads They are also resistant to shearing and tensile forces, thus maintaining their integrity even under heavy loads They are also resistant to shearing and tensile forces, thus maintaining their integrity even under heavy loads They are also resistant to shearing and tensile forces, thus maintaining their integrity even under heavy loadsstainless steel self drilling metal screws.

20mm chipboard screws typically feature a coarse thread, which allows for quick penetration into the board without causing excessive strain on the material. Their length, 20 millimeters, is ideal for most applications, providing ample depth for secure fixing without protruding through the other side. The sharp point at the tip ensures easy entry into the board, while the Phillips or Pozidriv head offers a secure grip for the driver bit, reducing the chances of slippage during installation.
