As we know, the most trouble thing in projects with self-tapping screw is to drill a hole in advance before assembling. There is also restriction on the hole diameters. It’s not cost-effective and a waste of time. It will definitely help and save your money if there is a way no need to drill the holes. Fortunately, there is a kind of screw which integrate drilling, tapping and spinning into one. That is self-tapping screw.
In general, self-drilling screws have high hardness, wide thread pith, proper thread depth. Compared to wood screws which have narrow threads, soft and blunt texture, self-drilling screws have much stronger drilling capacity with sharp tail, bold threads and high hardness.
Self-drilling has a drilling end design which is generally used together with a electric drilling machine. In this way, drilling, tapping and locking can be done at one time, thus efficient and cost effective.

Self-drilling screws are generally used in the connection of thin wood or metal sheets like color coated steel sheets, sidetimberpurline, wall beams etc.

Self-drilling screws are generally exposed outdoor which requires high rust-resistant performance, or it will be easily corrupt with time which brings high risk for the structure stability and waterproof performance.
