Self-drilling screws are easy to distinguish if you look at their point, which curves gently at the end and is shaped like a twist drill. They're often called Tek Screws, after the brand name that popularized them.
Self-drilling screws are generally easy to install and can be used with a variety of tools, including power drills and screwdrivers. However, it’s important to note that over-tightening can cause the screw to strip the threads, reducing its holding power. It’s also important to ensure that the pilot hole, or hole that the screw is inserted into, is the correct size and shape to ensure proper thread formation and holding power.
