size of screw for gpm steering knuckles?
 

i lost a screw from the gpm steering knuckles..they are a different
size than any of the screws that come with the xmod.

i even bought a bag of assorted 2-56 screws..but apparently
thats not the right size.

anyone have an idea?

I think they are M2x.4 .. I hope that helps. I also need to replace one and am waiting on those.

thanks.

I can definitively say that they are, in fact, M2x.4 metric screws. I ordered a bunch of various sizes for a chassis I'm building, risking that they were a different size, but that is not the case; they fit perfectly in the GPM parts.
BTW: Interesting buying story on them as I've been looking for standoffs and screws to match, and I've gotten quotes on those screws ranging anywhere from $1 to $5(!) PER SCREW for the suckers! Finally, I found them dirt cheap over at fastener-express.com, and they also have locking nuts that look surprisingly like TopCAD's for about $5 for 20.

wow. good find. just under 2$ for a bag of 50.
picked up a bunch of lengths for m2x.4
