So, you would use the same formula no matter what # the screw is? In
the above formula, the only thing that changes is the screw #?

so since
.0625 = 1/16
and
.0125 = 1/80
a #10 screw
would be
1/16 + (10*1/80) = 1/16+ 1/8 = 3/16?
interesting.
thanks.
And when are we going metric?????

I noticed that as screw diameters become smaller, they convert to #'s.
Would these be metric? For example you have fractional sizes, then 10,
8,6 etc.
No they are not metric BUT....... the major diameter (od over the
threads approx)
matches very closely to
.0625" + (screw size # ) multiplied by .0125"
check it out it helps me remember screw OD's
gets close enough
cheers

Yup! I kinda geeked out one day.....I actually curve fit screw OD's
in Excel to see if there was some sort of reasonable fit.....there is
within a thou or two.
your explanation ......
.0625 = 1/16
and
.0125 = 1/80
makes it easier to remember
cheers
