Fasteners are used to fasten two or more parts (or components) into a whole. They are widely used in various machines, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments and supplies. tools, instruments, chemicals, meters and supplies, etc. It is characterised by a wide variety of specifications, different performance uses, and the degree of standardisation, series and generalisation, It is characterized by a wide variety of specifications, different performance uses, and a high degree of standardization, serialization and generalization.
The screw is one of the most commonly used fastening parts, using the physical and mathematical principles of beveled circular rotation and friction of the object. Mathematical principles, step-by-step fastening tools for objects and machines. Drill-tail screws are a new invention in recent years. is a screw with a self-tapping drilled head at the front of the screw, it does not need to be used with the nut, also called self-tapping screws, the tail of the drill tail screw Drill-tailed screws are drill-tailed or pointed-tailed, so they can be drilled, tapped and locked directly in the setting material and base material without drilling holes in the workpiece first. The drill-tailed screw has a high pulling and maintenance force compared to ordinary screws, and will not loosen even after a long period of time. It is easy and safe to use. The drilling and tapping is done in one operation, saving time and labour. Drill-tail screws are mainly used for fastening metal plates such as steel plates. They are generally used for locking metal plates and non-metal plates, such as silica-calcium plates, gypsum boards and various wooden plates directly fixed to metal plates. metal sheets. The reasonably designed drill-tail screws enable the metal plate and the mating plate to be firmly locked together, avoiding damage and scratching of the mating plate, The screws are easy to install.
