Nikon d5100 tripod screw too small?

I just got a nikon d5100 and when attached it to my tripod it screws perfectly but not till the end so the camera is completeley loose. Comparing it to other tripod screws, I realized the socket on the nikon is indeed considerably less deep than the rest which fit perfectly my tripod mount.
I guess I can fix it putting something in between the tripod and the camera but I want to know if this is something normal on a brand new Nikon DSLR.

Added (1). It is probably the tripod being for something bigger (very very old tripod) but the fact that it works with 3 other cameras makes me wonder. Working cameras: GoPro, Canon point and shoot, Praktica B200.
Today I tried another fancier Point and Shoot and a Canon G15 and both are loose too but not so much like the nikon. Measuring the (nikon) socket depth it is at least 2mm shallower.

Sounds faulty, either the tripod plate or their is something in the screw hole? Tripod mounts are usually universal and definitely so on consumer DSLRS.

The screw is long and reaches the bottom of the screw hole of the camera threatening to puncture it and destroy the delicate electronics inside?

Go back to a camera supply shop and ask for the insert you are thinking of. Just tell them your case and they'll know what to give you.

No it's not normal. The tripod may be for something bigger - a broadcast camera, a huge telescope, or worse, a geodetic transit!

Some tripods that are designed for video use have slightly longer threads. Sounds like you have one of those tripods. The easiest fix is to get some gasket material at an auto store and make a pad on the top of the tripod mount, or perhaps you can get a photo head.

I'm pretty sure it is faulty. Just take it back to the store. Don't try to fix it yourself because then they may not do anything about it.

There's usually a ring round the screw between the bit you tighten and the plate on which the camera rests.screw the screw in as far as it will go then turn the ring clockwise until it tightens up. This ring is there to take up the 'slack'
