I don't understand what you're trying to make- screw heads stick out from the headboard? And you want to cover them, or you want to be able to turn them?
Here is a thumbwheel that I was using in my printer for bed leveling:
To make something like this, sketch with the big circle that defines the bulk of the thumbwheel. Now there are two ways to go- you can work on the sketch or you can work the 3D object:
Sketch: Draw a small circle on the edge of the big circle. Trim off the outer part of the small circle. Select the small circle and then select "move". Move the center of the axis reference (the thing with the arrows that pops up with the "move" command) on the center of the big circle. Click on "create patterns", then click on the blue curved arrow part of the move command axis indicator and move it until you start to see duplicates of the small circle arranged on the edge of the big circle. Let go of the blue arrow and then type in the "count" box the number of small circles you want distributed around the edge of the big circle- try different values- it updates as you type so you can see when it looks right, then hit enter. Now use the "trim" tool to delete the pieces of the big circle that aren't needed. Finally, pull it up as thick as you want and make a center hole.
3D: In 3D mode pull the big circle up into a disc as thick as you want it. Sketch a small circle on the edge of the big disk, then pull it down to take a bite out of the big disc. Delete the surface of the remainder of the bite's circle. Select the "move" command, and select the wall of the small bite you just created. Move the center reference to the center of the big disc, select "create patterns", use the blue curved arrow to pull a copy of the bite around the disc a few degrees, let go, type in the number of bites you want distributed around the circle (say 20) then hit "tab" and enter 18 degrees. (18 x 20=360 so you'll get a full circle of evenly spaced bites if you want 30, use 360/30 = 12 degrees, etc.). Finally, drill a hole or whatever you need to do at the center of the thumbwheel.
