1. Self-tapping ability of self-tapping screws
The "self-tapping ability" of self-tapping screws refers to the ability of the nail head to drill directly into the threaded hole. This ability makes the use of self-tapping screws easier and faster, and their strength is more reliable.
2. Self-locking property of self-tapping screws
The thread and tip of the self-tapping screw adopt a special design, which makes it self-locking during the fixing process, which greatly improves the safety and stability of the self-tapping screw.
3. Chipping of self-tapping screws
When the self-tapping screw is fixed, chipping will occur, and the chipping ability will directly affect the service life and fixing effect of the self-tapping screw. Good self-tapping screws have obvious chipping effect, while bad self-tapping screws are more likely to scratch the base material during chipping.
4. Material and surface treatment of self-tapping screws
Self-tapping screws for different purposes have different materials and surface treatments. For example, stainless steel self-tapping screws are suitable for use in humid environments, galvanized self-tapping screws are suitable for environments containing harmful gases such as carbon and hydrogen sulfide, and galvanized self-tapping screws are more suitable for use in dry and less corrosive environments .
5. How to use self-tapping screws
Self-tapping screws can be used manually and mechanized, and remember that during use, attention should not be too great to avoid damage to the base material.
