Fascinating.
Here is my version of a screw, above the stereo.
And I did use subsurf…..

Sometimes we get so involved in what we are modelling I wonder if the hour I spent modelling one screw to get it looking good close up , was it worth the extra verts. Which one are you?? I wouldn’t call myself an extrovert, per se, but I wouldn’t say introvert either.
