When thin nut is used, it is not used alone, but with another standard nut, which can play a role in preventing loose.When two thick and thin nuts cooperate, there are certain operating specifications.

We can also see from the above table that the thin nut should be placed in the front, that is, the thin nut should be screwed in first, and then the standard nut should be screwed in the back.

Only when the position is placed correctly, the anti-loosening effect will be better.

But in many cases, the installation operation process will not pay attention to this matter, often put the wrong position, so many enterprises in the procurement, direct use of two the same standard nut to install, although this will increase the procurement cost, but also effectively prevent the wrong installation situation.

The anti-loose effect of spring cushion

Some enterprises in the installation process, in order to save costs, only use a spring pad to increase the anti-loose effect, in fact, is not desirable, after a lot of tests show that, with the spring pad anti-loose effect, can only maintain about a week, as long as the equipment appears a little vibration, the role of the spring pad disappeared.

So the combination of a thin nut and a standard nut is currently the most effective and convenient way to prevent looseness.We only need to pay attention to the two nuts that are rotated and tightened separately.

Do not screw the first thin nut into the second standard nut immediately after it is tightened. This will not achieve the anti-loosening effect.

As long as the first thin nut is not tightened, the standard nut behind, no matter how tight it is tightened, will not work. When you go back, you will find that the two nuts can easily be withdrawn at the same time, and there is no stress standard to prevent loosening.

Under normal circumstances, as long as the first thin nut is tightened, and then tighten the second standard nut, there will be a lock effect, if you want to remove it, it is necessary to use the handle to withdraw the last standard nut, the thin nut will become loose.
