Hobby shops sometimes carry trox screws that size. Otherwise mcmaster.com has just about any size you can think of.
Actually, I am mostly looking to replace the BASE screws - all 4 of them are messed up & then just 1 of the rings screws is messed up - so I want to replace that one also.
The screws that are currently in the BASE are just plain single cross-sloted screws and so are the rings' screws. The screws in the base are a good bit bigger than the ones in the rings.
