Can anyone shed some light on how to order metric bolts?  It looks like the
common Grades are 8.8, 9.8 and 10.9.  What Grade should one use for
structural fastening of motor mounts, etc?

If you need bolts that are partially threaded is there a way to specify the
length of the unthreaded portion?

Should we be using mil-spec bolts and does anyone have a reference to
locating metric bolts using a mil-spec number?
