Gentlemen,
If you don't care about fastener minutia, then stop reading now.
Slotted vs. Castellated nuts

Slotted nut

This image says it's a castellated nut but is in fact a slotted nut!

Castellated nut

A good number of the images on Google claim slotted nuts are castellated nuts
and vice versa, so you obviously cannot trust the web on everything.
Bottom line... the official source is the Machinery's Handbook. My 16th
Edition,1959 volume printing clearly shows the distinction. It also has quite
a bit of info on Whitworth Fasteners and UNF, UNC fastener markings that
distinguished them from Whitworth.
Cheers,
Curt

Depends on what you get supplied, slotted nuts have the 'slots' more or less
half the height of castle nut 'slots' and as you point out they are different
animals, And yes the correct bmc fastener is a slotted.
I stand corrected, just pointing out its usually easier to run a standard
nut down it first, then replace with the correct one.
cheers
Andy
