Hex Nut Manufacturers describe which nuts can be used on aluminum profile frames:

1. The installation of the T-type nut is to put the nut head into the groove in the direction of the profile groove, and rotate it 90 degrees clockwise. During the installation process, it can be automatically positioned and locked.

2. Elastic nut and shrapnel nut. The installation method of these two nuts is the same and can be directly inserted into an assembly point in the groove of the aluminum profile. The spring steel ball on the back can fix its position, making the installation very simple and reliable.
