Is the Nikkor AF-S 35 mm 1.8 DX compatible with the Nikon d800?

I was under the impression that most any Nikon lens (being all F mounts) would be interchangeable between DX and FX cameras. Yet my 35mm, which was bought for a DX camera, will not attach to the d800. Though I line up the indicators, I can t twist it into place without getting some serious resistance. Attaching the same lens to my DX camera is a breeze and requires very little force. The same is happening with my Nikkor AF-S 55-200 mm 5.6 DX lens, and with my Nikkor AF-S 18-55 mm 3.5 DX lens. Are all of these incompatible with the d800 or am I missing something obvious?

Added (1). I observe that “big image sensor size” word are just use for marketing purpose but reality is Lenses quality and other factor even I observed that camera with small image sensor but with 4K video are giving better image quality then those which are with big size sensor.
