Screw: The Most Commonly Used Fastening Component
A screw is one of the most widely used fastening components. It is a tool that secures objects and mechanical parts step by step, leveraging the physical principles of inclined-plane circular rotation and friction, as well as mathematical principles. By converting rotational force into linear clamping force, it applies controllable pressure to form a stable connection, making it an indispensable part in the assembly of machinery, equipment, and daily-use products.
Drill-Tip Screw: A New Invention in Recent Years
The drill-tip screw is a new invention in recent years. It is a type of screw with a self-tapping and drilling head at its front end. It does not need to be used with a nut, so it is also called a "self-tapping screw". The tail of the drill-tip screw is in the shape of a drill tip or a pointed tip. There is no need to pre-drill holes or tap threads on the workpiece first; it can directly drill holes, tap threads, and lock on setting materials and base materials. Especially in the connection of all places such as construction, architecture, and residential buildings, the self-drilling and self-tapping screw is the best economical fastener in terms of workability, cost, and reliability.
