Shower frame replacement screws

[jdarwin]

Does anyone know what type of screw this is?

It’s rusting out. I went to remove replace them with stainless steel screws and noticed it has a long shaft with no threads. I was afraid to completely remove for fear of a nut or some other device holding it against the wall coming off. If this was a S&B it would have been a panhead wood screw in a stud. Because I’m unfamiliar with RV construction I don’t want to make things worse than they already are. Thanks

Hmmmmm…..I will be following this thread.


Can you measure from both walls and look on other side to see?

3" cabinet screw, replaced 3 on each side of frame and 6 on the shower grab bar.

Behind the shower is a wall


The wall is about 2 inches thick and 4 inches including the fiberglass shower
