It didn't really click to me until recently that the stand I just built for a 75 gallon tank has these screws going into treated 4x4's. How long can I expect before the screws go bad? should I even sweat it at this point?
 
drywall screws are not strong. I'd be more worried about the weight snapping them, than the screws rusting out. I'd redo it asap.
 
I wouldn't worry about it too much. As long as the stand is built correctly, the screws are just simply holding things together. The idea is that eventually they will give out, but I bet you have some time.
 
They are weak and will split the wood. Tried using them when I built a canopy. Didn't work. I ended up having to buy materials twice. Stick with wood screws or nails.
 
Regular screws won't last even 2 years in today's pressure treated lumber. You have more than a few months, but I'd go through and replace them pretty soon.

In all honesty you should replace the pressure treated lumber, it releases highly toxic fumes for up to a year. pressure treated lumber should only be used outside. Its not really any stronger than regular wood, just resistant to rot.
 
Unfortunately, I might have a 75G stand available if you need one.

is that right? is it a wood stained one? let me know and I will just sell this one.
 
does treated lumber really give off toxic fumes? I'm not sure that is accurate. Anyone else?
 
I'm not sure if it gives off fume, but it does contain chemicals with which you should avoid making skin contact.

I believe that the real concern is with particles becoming airborne while cutting.

I also believed that it was only a concern with skin contact. I dismissed this as the entire stand is skinned so there is no exposed frame. I may just replace the screws however I am concerned if the stand gives off fumes. I may buy a another one or build a new one as this is 'cabinet' style and my daughter wont let the stuff stored on the shelves alone.

Any more thoughts on the fumes given out of the wood?
