nylon breakaway screw for rudder - where to buy

I've seen several MG29's with a nylon breakaway screw in the lower rudder bolt hole. I would like to change mine to that setup. I know it is a simple question, but where do you buy that screw. The only 3mm nylon screws I found were too short.
Thanks,
Bob

I get mine from ebay. Any size you need:

near the bottom of page. Probably not cost effective unless you need some more stuff.

Thanks!

I use a 4mm one.I found the 3mm allows the rudder to move a bit.I'm probably a little late here,Sorry

No problem, thanks for the input. I saw on e-bay (from post above) you can get a packet of 100 relatively cheap, so I will have a lifetime's supply :biggrin:
