You can buy Ti screws at McMaster carr. Really expensive idea just to hold on a cover.

Or you could get plastic ones at Home depot or Lowes for a couple of bucks.

good choice on changing out those screws... there are a couple people here who's reef tanks suffered from the screws that eventually rust. instead of going with the titanium i did the plastic screws from home depot.. they work great...

This was posted from solbby on the mag drive thread.... (thanks again Solbby i found them at home depot and they work great)

INFO ON MAGDRIVE NYLON SCREWS:

Screw size information for Magdrive pumps: 440, 632, 832, 1/4-20 on the link I gave should write like 4-40, 6-32, 8-32, 10-32.... The first number stand's for diameter of the bolt, while the second number stand for number of threads per inch. Example: 1/4-20 is a bolt 1/4" dia. with 20 thread per inch. Screw that have diameters smaller than 1/4", one will use number instead ( 4, 6, 8, 10 ) Ex: 8-32 is mean screw size 8 with 32 thread per inch.

So the 8-32's in 5/8" or item number 91480 (5/8"L x 832 Thread Nylon Round Head Slotted Screw) are the ones to order for Mag's 3-9.5, .

I don't have any information on Magdrives above 9.5. So your going to have to measure the screw length and thread count yourself (I don't own these pumps, so I never researched them).
