At the same time I bought a thing of pop rivet fastener company, but it seems to be exactly the same thing. Both markings are written as POP. (It is not a mistake in seeing TOP) It may be an OEM item. I tested both products properly by caulking both products properly, but both things are the same or both can be used properly. I do not sell small blind nut M3, so I think it is valuable.
I installed it in the aluminum carport frame. By attaching a round hook (screw type), we try to hang sunshades and others. If summer is over it will remove the sunshade, but use the hook as it is. It may not be able to withstand a large load because it is aluminum, but now it is comfortable to use.
The screw hole that had been opened in the aluminum sash was enlarged and it was not useful to change the size of the screw head so it is useful for using the same size. Because it has some thickness, I use it somewhat modified.
It was used for interior installation of a light van. I used a steel plate with an appropriate hole and capped using M5 bolt. Using the electric impact screwdriver makes working easier but if you use the same bolt too much, the bolt broke in about 4 times so I think that you can work without waste before replacing the bolt before it breaks.
