I don't find a problem with mine. The metal hoods seem to go on much better than the plastic ones. You need to line it up (the white dot on the hood against the white line on the lens and then a 1/4 turn.
It depends what mount the Tokina lens is. I find the K&F ones work well.

The newer version has WR, better stabilization, a numbered aperture ring (original had ring but you had to look at screen for f-stop), and a lock for the auto setting on the aperature.
