Backplate hardware thread size

[tcartwright81]

I've got a losi mach 427 and a 454 I need backplate screws but for the life of me find the size and pitch any body have a thought? All losi kits are discontinued ?

get a thread gauge and a micrometer ...then youll need a machinist tool handbook or the internet . more than likely they are metric

Pretty sure they are just standard 3mm cap heads. Been a while since I had one to take apart though.

Found the 427/M26SS screws on ebay though, listed as the same part for a few engines:

Oddly, the 454 screw set comes with all the screws vs just pull-start/backplate, part number LOSR2228. Didn't see that set, but they look the same.

Maybe these would work?

Could chuck them up in a drill, then run them against a dremel or file to grind them down so they aren't so large.

They are used as servo mount screws on traxxas vehicles to spread the load on more of the mounting ears vs using a bolt/washer.
