[R-390] Bristol Screws for R390 Knobs

Fri, 21 Feb 2003 06:31:18 -0600

Carl,

Last night I measured them with my screw pitch gage and, sure enough, they are #8-36 UNF.  I should have checked that out before I bought these.  They are #8-32 UNC as advertised so I have no one to blame but myself.

A few weeks ago, I sent a post telling about a guy who has some
Bristol-drive set screws for the R390[A] knobs.  I ordered a couple of sets
and it turns out these are not the correct thread size.  They are close, but
not quite right.

They were advertised as #8-32 but I don't think that's what they are.  I
haven't measured either screw yet, but I have a feeling these most likely
are a metric size that is very close to #8-32.

At any rate, if you are thinking of ordering these for your R390, they won't
fit!

My apologies, but I was led to believe these are something they are not.
Needless to say I will be contacting the seller.

Thanks,
