Screw Knowledge
Screws, often referred to as "screws" or "bolts," are one of the most commonly used fasteners in both industrial and everyday applications. Despite being called by similar names, screws and bolts are not exactly the same. A screw typically has a pointed tip and is used for fastening wood or plastic materials, with a larger thread pitch. On the other hand, a bolt usually has a flat head and is designed for metal or mechanical parts, featuring a finer and more uniform thread.
The use of screws dates back thousands of years and is considered one of the earliest human inventions. They have become essential in various fields such as construction, manufacturing, logistics, and even scientific research. From cutting tools to safety equipment, screws play a vital role in ensuring stability and precision in industrial products.
One of the main functions of a screw is to provide a fixed unit of height, ensuring that components fit together securely. If the threads don't align properly, or if the screw head breaks during use, it can lead to structural issues. This highlights the importance of high-quality screws, which are mass-produced with consistent accuracy. Typically, screws are manufactured to a standard of 6g (equivalent to level 2 in the American standard "IFI" - 2A), while coarse screws used in construction meet the 8g standard (level 3, "IFI" 1A).
The value of a screw might seem small, but its impact can be huge. There have been real-world examples where poor screw quality led to major failures—such as car factory bankruptcies, aircraft crashes, and vehicle accidents. These incidents emphasize how critical it is to ensure the reliability and quality of even the smallest components.
While screws may seem simple, they significantly improve our daily lives. When used correctly, they offer great convenience and efficiency. However, improper handling or low-quality screws can cause problems. Therefore, it's important to choose the right type of screw for the job and ensure proper installation.
