Screws
Screws are critical fasteners in mechanical connections, and their basic structure can be divided into four parts: the head, the shank, the thread, and the tip. Types of screws can be classified based on their use, including self-tapping screws (tapping screw or self-threading screws), machine screws, wood screws, metal screws, and set screws. Common screw head types include pan head screws and hex screws. The materials used for screws are usually metallic, such as carbon steel, stainless steel, and alloy steel, as well as non-metallic materials like wood and plastic. When purchasing screws, one should consider the size, thread type, and coating; during installation, it's important to use a screwdriver for pre-drilling, torque control, and maintaining cleanliness. Regular checks and replacements can ensure the longevity of screw fasteners. By selecting and using screws properly, the stability and safety of mechanical connections can be effectively enhanced.
