[ARC5] 3-48 screws

[Michael Hanz]

I was with you all the way until the last sentence, Ken, but not because 
I'm feeling argumentative.  Ronnie was specifically looking for screws 
to hold the four Lord shocks on the mount.  Attached is the build sheet 
for one of the 274-N mounts just for example, and all  of the sheets 
specify a Phillips head screw for some reason. Must be one of those 
mysteries of science.

On a related subject, I haven't had good luck with the fit and finish of 
the Ebay 3-48 stainless screws compared with the ones from 
McMaster-Carr.  They don't tolerate "oops slips" very well either, so I 
stopped using that source almost as soon as I tried them.  But I guess 
"ya pays yer money and ya takes yer cherce"...
