Self-threading screws, also known as self-tapping screws are designed to cut their own thread as they are driven into materials, eliminating the need for pre-drilling.
They come with a distinct feature: the end of the screw has a cut out in it. This unique cut allows the screw to carve out its own threads. When you're threading the screw, you might notice increased resistance once you pass the little cut in the screw. This is normal and indicates that the screw is forming its own thread.

Tips for Using Self-Threading Screws
-
Expect Resistance: As mentioned, you will feel more resistance once you pass the cut in the screw. Be prepared to use some extra muscle to get these screws fully inserted.
-
Patience and Pressure: Apply steady pressure and take your time. Rushing can lead to stripped threads or broken screws. Use a screwdriver that matches the screw head to ensure a secure grip.
Example of where you may start to feel resistance:
Assembly Tips
1. Align Brackets Properly: Before fully securing the screws, ensure that the brackets are facing up and are straight. Misaligned brackets can cause instability and uneven surfaces. Take a moment to double-check their position before driving the screws all the way in.
2. Secure Screws Out of Order: When assembling furniture like a desk, start by securing the screws to the top of the desk out of order. This means attaching one screw to the top and then moving to another screw on the opposite side or corner. This technique allows you to manipulate the legs more easily to align with the screw holes.
