Hello, I have used ESSVE brown plastic plugs for concrete/brick/natural stone when mounting a heat lamp on the facade of my house.
The wall I believe is made of a layer of plaster on the outside and then some form of concrete/stone. After about 3-4cm, there's a cavity.
The lamp weighs about 4kg, hangs on 4 horizontal 4.8x45 screws, and it feels secure, I can pull and tug quite hard without it moving.
Still, I am somewhat worried that it might fall after some time due to the wall/plug and possibly take parts of the wall with it.
I've considered using thicker screws with a 5.5-6 diameter but would prefer not to replace the plug since I don't want to risk worsening the fit between the wall and the plug. Can I reuse it with another thicker screw or will that cause problems?
What do you think, do I have reason to worry or is it just in my head? As I said, it seems very solid at the moment.
The plug is specified for 4.8-6 in screw diameter.

If it fits well, it fits well. A larger dimension of the screw will not make any meaningful difference. However, you will have a worse plug in the wall if you change the screw.

No, I don't think there's any risk at all...
The risk with switching to a coarser screw, however, is that you might crack the stone around the hole when the plug can't expand...
If you're really nervous, use chemical anchors and stud bolts.
