Assembling a TT-02 with RC Screwz hex head set... The M3x10mm are too long for many of the holes. Not only that, they have 2.0mm hex sockets (pockets?) rather than the 2.5mm I think is more common on M3 screws. The 2.0mm are highly prone to stripping. Pulled some M3x8 cap head screws out of my electronics parts drawer and they fit MUCH better. The cap head may or not be a problem in any location but I can't see an issue yet.

I am not very happy with this screw set especially at the cost. I think it was something like $35. For that I at least expect perfect fit and hex sockets that won't strip! It's like $10 ($5? less?) worth of screws, at least pick perfect ones for the kit. Or am I missing something?

edit: Yeah the 2x8mm are even worse screws. They are slightly too long for the holes (at least some of the holes) and they strip really easily. This is NOT at all what I was expecting from such an expensive screw set. It's actually ruined my rear diff!
