How to get the self-tapping screws is the easiest?
Dec 26, 2018

The biggest feature of self-tapping screws is that they do not need to be used with nuts. They can rely on their own thread locking and connection. They are a kind of screw that is very common and commonly used in daily life. When the self-tapping screw is screwed into the hole in the plastic metal material, the internal thread can be formed in the hole by the action of the extrusion, which is the secret of the self-tapping self-drilling of the self-tapping screw. Among them, a special self-tapping screw for metal hole opening is called wire tapping.

In fact, the screws can be used with gas batches, screwdrivers, gun drills, and electric hammers. Generally, it is necessary to use electric hammers when entering concrete. Concrete walls marked with C10 or above cannot be nailed with ordinary nails. If the bearing capacity is not high, cement steel nails can be used directly; if the load-bearing requirements are high, expansion screws are needed, and ordinary plastic expansion pipes are fixed with self-tapping screws.
