Hex-bolts holding the Replicator 1's stepstruder together: What are they?

[Eric Pavey]

I'm building a extruder cooler for my rep1 single (many designs for double's online, no singles I can find).  Design is done, I just need some (1cm) longer hex-bolts to strap it to the stepstruder through the standard cooling fan holes.  I measured them: 47.6mm long x 2.88mm shaft OD.  The cap OD is 5.35mm.   I'm not sure what they are though (been searching), can anyone clue me in: Metric\standard?  Do they go by a given name, like M3 or something?

Thanks!

Probably these M3x60 cap screws from McMaster.

Pretty much everything should be M3 cap screws.
