[TheForge] Fw: Fw: Machine screw size?

Wed Jun 24 07:05:55 EDT 2009

Jeff,  It is very likely a M5 x 0.8 metric.  That is very close to a 10-32 
but will not run because if I did the math right it is 31.75 threads per 
inch.  This is a common size on bikes or you can re-tap to 10-32 if you 
can't find a M5 x 0.8

Dave
