Galvanized bolt and colored zinc blue and white galvanized bolt: the in-depth analysis of the whole tooth, half tooth and the extended combination of the outer hexagon screw

When we talk about bolts and screws, the first thing that many people come to is their basic purpose —— connecting and fixing objects. However, with the continuous progress of industrial technology and the expansion of the application fields, the types and specifications of bolts and screws have become more and more diversified. In this article, we will focus on the characteristics and applications of galvanized bolts, colored zinc blue and white galvanized bolts and whole tooth, half tooth and extended external hexagonal screws.

First, let's learn about the galvanized bolts. Galvanizing is a common anticorrosive treatment technique that effectively prevents a protective layer of zinc on the metal surface by forming a wet and corrosive environment. Galvanized bolts are treated on the basis of ordinary bolts, so as to improve its corrosion resistance and prolong the service life.

Next, let's look at the color zinc blue and white galvanized bolts. Color zinc blue and white galvanizing is a special galvanizing process, the zinc layer formed by it has a unique blue and white Ze, not only beautiful and generous, but also the anti-corrosion performance is superior. Color zinc blue and white galvanized bolts maintain high strength and good mechanical properties, but also have excellent corrosion resistance and decorative, widely used in construction, automotive, electronics and other fields.

In addition to galvanizing treatment, the tooth shape of the outer hexagon screw is also a key factor in its performance. The difference between the whole tooth and the half-tooth screw mainly lies in the integrity of the thread. The whole tooth screw thread is complete, from the head to the tail all have a thread, suitable for the need for stronger connection force and higher sealing occasions. The screws are only partially thread, usually used to connect a thicker material or need to allow space to install other parts.

In addition, in order to meet the needs of different lengths, the outer hexagonal screw also has an extended type of options. Extended screws are usually used to connect two distant objects, or when greater pretension is required. By increasing the length of the screw, the risk of stress concentration and deformation caused by excessive pretension force can be reduced while maintaining sufficient connection force.

To sum up, galvanized bolts, colored zinc blue and white galvanized bolts and the whole tooth, half tooth and extended combination of outer hexagon screws have their own characteristics and are suitable for different application scenarios. When selecting and using, it needs to consider the specific engineering requirements and working environment to ensure the safety and reliability of the connection. At the same time, with the continuous progress of materials science and technology, we also look forward to seeing more innovative bolt and screw products appear in the future, to provide strong support for the development of various industries.
