What is the screw size required to attach half rack devices (i.e. DMP2, Roland JV-1010) to a universal rack shelf? My DMP2s didn't come with one!
Thanks!

Personally I don't know the size,however,I use standard 19"
rack SHELVES for un-rackable equipment.

Well, the DMP2s are made to be mounted on a 19" shelf but what do I secure the DMP2 with? There is a hole in the bottom of the DMP2 (as is on my JV-1010) for attaching to a universal shelf but I just don't know what screw size to use 
Thanks anyway...

Start off with standard rack screws and take it from there.

If you can't fix it with duct tape, get something you can.

I don't think there is a standard for that type of screw, but finding the right one is simple. You go to a hardware store with the object in question, and you find a screw with a size that seems to fit, and the you GENTLY try to screw it into the hole. It should go in easily, with a nice fit, but requiring no force.
When it comes to Japanese equipment I'd try the metric sizes first.

The few pieces I have used have required 8-32 and 10-32. 8-32 is probably pretty common, but Regebro is right about the Japanese gear: assume metric. If you use a screw, make sure that you use the shortest possible length: in some products, the PCB does *not* have a clearance hole for the mount screw, and using a too-long screw can short PCB traces to the case. Not good.
The universal rack shelves and half-rack units never seem to have countersunk holes to allow a mounting screw head to sit flush, so even a flathead screw will make the screw/shelf/unit stack too tall to fit into a true single space, and will hang up on the gear below. Another issue is that half-rack pieces usually have only a single center hole, which means that they can rotate a bit on the screw, causing it to loosen over time. With all those hassles, I just gave up. I use 3M's thin doublesided foam mounting tape, and just stick them down on a nice cheap blank shelf. Usually, Velcro will also make the stack too tall. If I need to move them, I just peel them up...
