The process begins with drilling a hole in the drywall to accommodate the bolt's anchor. The butterfly bolt consists of two main parts the bolt itself and the spring-loaded wings. When inserted into the pre-drilled hole, the wings collapse, allowing the bolt to pass through the drywall. Once the bolt is pushed through and the nut is tightened from the front side, the wings expand against the inner surface of the drywall, creating a secure anchor point. This design ensures that the bolt not only holds the weight of the mounted object but also withstands any pull-out forces.

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.

Another compelling advantage of self-drilling screws is the secure fastening they provide. The design of these screws allows for a strong bond between materials, ensuring that connections hold up over time. The 2-inch length is particularly useful for thicker materials or applications requiring additional grip. The deep threads and robust shaft of these screws help enhance their load-bearing capacity, making them an excellent choice for high-stress applications.
