As a stand-alone image, I'd crop it. I like the "ghosts" in the background, but they are just not interesting enough to carry the top part of the frame.
The only exception would be if you had a series of these shots with tons of dead space, and the objects constructed a sort of narrative or borrowed from a pre-existing one.
A neutral surface for the screw or one which would support where a screw might be used would have been infinitely better. Too much going on after the lighting and composition to keep my attention. Screwed up on this one, me thinks.
I suppose it could be the start of a "fastener" series. I tend to agree with the earlier post about the "ghosts" in the shadows not quite working. I think you may be close to something here but you need to do more with the background.
Ohhhhhhhh, a fastener series! As Austin Powers says, "Yeah baby, yeah!!" Imagine the possibilities as amolitor prowls the aisles of Home Depot....nails...galvanized nails...titanium-tipped nails ...roofing nails...oh, just the nails alone makes me feel weak in the knees. Then there are all the staples and such! staples_zinc_diamond_pt.jpg Not to mention all the screws! Both tamper-resistant and standard head types. The whole fastener field seems just ripe for a series of photos!
