Door Buttons
OK, so I am replacing a couple of Perko "Door Buttons" and the ones I got (on Ebay) say they are supplied "without spring and requires a no. 8 oval head pivot screw". So, the plastic knob right now just will fall right off. Problem is I can't figure out what an oval head pivot screw is. Can anyone help me out? See photo below....

Its just a screw with a non threaded shaft for the plastic handle can turn with out getting caught on the threads.
I believe that you might be able to put the bolt Thur the plastics knob and a nut on the back, then screw to the boat? Or just run a bolt Thur the plastic knob and screw to boat but not tight all the way so it can move. Its easy baby, just don't think so hard

An oval head is just like a flat head (like the screws that hold the door hinges to the door and jamb in your house), except that the head is slightly rounded - it humps up a little, rather than sitting flush with the surface it's screwed into. They're asking for the oval head because it gives a nicer finished look - a flat head will work fine, but like MJ says you want one with some non-threaded shank to keep from wearing out the hole in the plastic gizmo. Use a screw or MJ's machine screw with a nut and a little thread lock (or a second locking nut) so it stays put, but use a good stainless one.
