I don't see a FLM screw kit. I know FLM's parts comes with alloy steel grade 12.9 fastners and where I've had a prob, the replacement part comes with the same complement of fastners just like the orig did.
If you're just looking for a screw kit, try Tony's, I get all my rc fastners from Tony. It's usually the 1st thing I do when I get a new rc - replace all the screws with high strength alloy steel hex heads.
