Self-tapping screws can be used in many fields. The difference between self-tapping screws and ordinary screws is that ordinary screws must have processed screw holes before they can be screwed in. Self-tapping screws do not need to be tapped while screwing in.
Custom self-tapping screws
Self-tapping screws are generally fingertip, coarse-tooth, and hard wood screws. Self-tapping screws are mainly used for the connection and fixing of a thinner plate, such as the connection between color steel plate and color steel plate, the connection between color steel plate and purlin, wall beam, etc. It also has aluminum alloy and plastic, which is used for non-metal or Softer metals do not need drilling and tapping. At the same time, self-tapping screws are pointed. They can "tap, drill, squeeze, and press" the consolidated body on the material to be consolidated, relying on its own threads. "Out of the corresponding thread, so that they fit closely with each other.

Self-tapping screw is a kind of screw with a drill bit. It is constructed by special electric tools, and drilling, tapping, fixing and locking are completed at one time. Self-tapping screws are mainly used for the connection and fixation of some thinner plate parts, such as the connection between color steel plates and color steel plates, the connection between color steel plates and purlins, wall beams, etc. The penetration capacity generally does not exceed 6mm, and the maximum does not exceed 12mm. Tapping screws are often exposed outdoors, and they have strong corrosion resistance; their rubber sealing rings can ensure that the screws do not seep water and have
Good corrosion resistance.
Custom self-tapping screws
Self-tapping screws are usually described by three parameters: the screw diameter series, the number of threads per inch of length, and the length of the screw. There are 10 and 12 series of screw diameters, and the diameters of the temple screws are 4.87mm and 5.43mm respectively; the number of threads per inch is 14, 16, and 24, and the number of threads per inch is more.
Its self-drilling ability is stronger.
Self-tapping screws have high hardness, wide thread spacing, deep threads, and rough surface, while wood screws are the opposite. Another difference is more obvious, and there is no thread at the back of the wood screw. Wood screws have fine threads, blunt and soft points. Self-tapping screws have thick, sharp and hard threads.
