Common sense of installing fasteners

Fasteners are particularly important in solar mounting brackets. If the solar panels are loosened due to incorrect installation, it will cause great losses.

Today, let's discuss the correct way to install fasteners.

First of all, the spring washer needs to be placed behind the nut, so that the elastic force of the spring washer can be used to increase the friction between the nut and the bolt to prevent loosening.

Second, flat washers must be placed under the bolts and nuts to increase the pressure-bearing area. If there are spring washers installed, the spring washers need to be placed on top of the flat washers, closer to the nuts.

Third, the number of flat washers should not be too much. If there are only bolts, only two flat washers can be placed at most. When there are install nuts, only one flat washer can be placed. If there are too many flat washers, it may loosen.

Although the above is the installation master's common sense, if you need to install it yourself, you need to pay more attention to the above installation details. Don't make mistakes because of carelessness. Small mistakes will affect the smooth operation of the entire project.
