Reasons and Solutions for the Loosening of Industrial Aluminum Profile Bolts

Industrial aluminum profile frame products are mostly connected by industrial aluminum profile accessories, unlike steel profiles that require welding. This accessory connection method is clean and beautiful, and saves time and cost, which is the preferred connection method for most users.

The most common type of connection is the industrial aluminum profile bolt combined with a nut or angle connector/corner fitting. These connections are sturdy and aesthetically pleasing.

However, sometimes the bolts at these connections may become loose. In such cases, what should be done to solve the problem? We have compiled the following information:

Reasons for loosening of industrial aluminum profile bolts:

• After tightening the industrial aluminum profile bolts, over a period of time, they may become loose. At this point, personnel need to regularly check the bolts at the connection points and re-tighten any loose bolts.

• When threading the holes of industrial aluminum profile, if the depth of the threads is not enough, the industrial aluminum profile bolts may not be able to be tightened properly, resulting in rapid loosening of the bolts during use.
  

• The threads on the industrial aluminum profile bolts may be damaged. This could be because the quality of the bolt is not up to standard, or because the threading was worn out during use. When damaged threads are found on industrial aluminum profile bolts, they should be replaced promptly.
  

• The industrial aluminum profile bolts do not match the associated nuts, which is also a reason why the bolts cannot be tightened properly and may become loose. When using industrial aluminum profile bolts, they should be paired with the appropriate nuts to achieve a better tightening effect.
  

• Some industrial aluminum profile bolts require the use of elastic washers, such as hex bolts and semi-circular head bolts. Adding a washer can increase the contact area between the bolt and the industrial aluminum profile connection point and prevent loosening.
  

The above is a list of several situations that could cause the loosening of industrial aluminum profile frame bolts, along with the corresponding solutions. We hope this information is helpful to you!
