Nuts are also classified into grades, how to match with bolt gradesUpdate Date:[2020-05-20]
As for the fastener bolt, we all know that it is classified, but the nut is also classified. Do you know whether it is clear? Today, the Chinese standard parts net summarizes the relevant level analysis of the sensible nut. Of course, the nut is screwed together with the bolt for fastening, so how can we...Screw and nut: no matter how serious the rust is, I'll show you how to loosen itUpdate Date:[2020-05-20]
Screw and nut are also common fasteners in our daily life, but rust is also a common problem phenomenon of screw and nut, and it is the most desired way for us to screw out the rusty screw and nut easily. According to the understanding of screw and nut knowledge, China standard parts network, here, sh...Prevention measures of stainless steel bolt and nut seizingUpdate Date:[2020-05-20]
From the previous analysis, it can be seen that it is very inconvenient to disassemble the stainless steel fastener after it is killed. Even some methods or special tools are time-consuming and laborious, so it is particularly important to prevent the stainless steel fastener from being killed. The followin...Why do stainless steel bolts and nuts bite?Update Date:[2020-05-20]
According to the use performance characteristics and functions of fasteners, the fasteners used in many fields will be made of stainless steel, and the most common disadvantage of stainless steel fasteners is that in the process of use, the bolt and nut can not be unscrewed after matching, which is called "s...Technical difference between hot galvanizing and cold galvanizingUpdate Date:[2020-05-20]
Technical differences between hot galvanizing and cold galvanizing: The corrosion resistance of hot galvanizing is much higher than that of cold galvanizing. Hot galvanizing will not rust in a few years, cold galvanizing will rust in half a year! The cold galvanizing process is used to protect th...What is the performance of nutUpdate Date:[2020-05-20]
There are many kinds of nuts. Now let's talk about the hydraulic nuts in detail. What are their performance advantages?
