Default The cylindrical frame spacers...

They are so tricky to get loose.

You put a driver in the screw on one side and it just rotates instead of backing out. You put a driver in the screws on both sides and one screw comes out leaving the other one stuck in there...

They're super hard to grip with pliers, they just rotate and the screw stays locked in place...

Normally I have to heat them up with a blow torch in order to get the screws to turn loose with little enough force that I can hold them in place with pliers... (and of course there's fuel tanks etc made of plastic right there that you don't really want to be blow torching around!)

I think in future I'm going to use the square ones instead of the cylindrical ones because those ones at least you can grip with pliers while turning the screws out...

edit: nope the square ones (and the fan hex shaped ones) don't seem to be threaded deep enough...

I usually use a pair of lineman's pliers or channel locks to hold them.
If you haven't already, throw out the Gaui buttonhead screws. They're made of alumibutter. Use normal 6mm cap head hex screws instead.

If you need to, try either a soldering iron on the screwhead or a heat gun instead of a torch to break the locktite.

Yeah the gaui button head screws are pretty weak!! I've got them on there at the moment, but I bought a pack of socket head screws and I plan to replace the button heads with the socket heads as I remove them!

If you don't want to use heat, cut a slot with a Dremel blade. Then you can use a decent size flat-tip screwdriver. Always come out this way.
