Screws for a diy stand

  • We are currently upgrading MFK. thanks! -neo
I just built a stand like that. I used 3" #8 wood screws on the the 2x4. I used 1 3/4" # 8 wood screws on the 3/4" plywood and the 1x4 strapping. I pre drilled everything with a 1/8" bit.

I don't know how to add a page but you can look at 108 tank stand.

Good Luck
 
I use drywall screws. My 330gal tank is held by drywall screws. The 330 stand is held by drywall screws. My old 180 before I threw it out was held by drywall screws. Turtles stand is held by drywall screws.
 
Proper wood screws have an unthreaded portion on the shank which is designed to turn freely in the piece closest to the head, while the threaded part engages in the other workpiece. This causes the workpieces to be pulled tightly together as the screw is tightened. Drywall screws are threaded all the way up, causing the threads to engage on both workpieces which can prevent them from being pulled tightly together or "jack" apart as it is tightened. Drywall screws are also tempered, to make them harder and thus resistant to stripping when used with screw guns. This makes them more brittle and prone to breakage when used for a structural application. For assembling 2x4's for aquarium stands, you should really use deck screws.
 
Bob, you are 100% right. Drywall screws are a poor choice for applications that need to bear a load (such as a tank). They are not designed to be used in this manner. If you're going to build a tank or stand, use some decking screws. 2.5 or 3" - whatever your design calls for.
