Have you tried booleans? I tried it out, cutting a cube into a deformed halfsphere. If you do, one suggestion I'd make is to make sure you keep a copy of your uncut screwhead so you can use it as a guide if you have to add 'roundness' at the sharp points where the box cuts. These are the points where you'll probably have to add a manual edge too. And don't be afraid to have a pretty dense mesh.

Depending on how close your camera is getting, you might be able to get away with just marking the edges as hard, but if you want to catch the edges better, make use of the bevel property page to fine tune your results. Bevel last.

Hope that helps some,

Are you using subdivision?

this might help : http://www.geocities.com/zukezuko/q2.jpg
with yellow are the new edges you should create,

or make a loft then do a boolean for the bolt
check out loft in your manual , its great....
hope it helps.
