Should I Use Self-Drilling Or Self-Tapping Screws?

The decision to use self-drilling or self-tapping screws is based on the specific application needs and material properties.

Here are some selection suggestions:

Material Hardness: Self-drilling screws are ideal for softer materials such as wood and plastic. Self-drilling screws provide more efficient installation for harder materials such as metal.
Installation Efficiency: If a large number of fastening operations need to be completed quickly, self-drilling screws are a better choice because they can complete drilling and fastening at the same time.

Equipment and Tools: Consider the installation tools available. If hand tools are used primarily, self-drilling screws are more suitable; if power tools are available, self-drilling screws can significantly improve efficiency.
Cost and Benefit: Self-drilling screws are generally more expensive than self-drilling screws, but their efficient installation process can save time and labor costs, making them economical for large-scale projects.
