it is for an old fashined door knob spindle,the thicknes is 9/32 square
stock, and 20TPI,is there a nut or bolt made for this thing? Thanx

I don't know what the thread is, but those things are so soft it usually
doesn't even matter. They'll mush in anything.

I can't believe this Jimmy, nobody can give you an answer,I thought
some great machinists are posting here.I heve seen this type of door
knobs in many houses built from the 1900s to 1940s.

Its not the quality of the machinist..but the quality and variability of
the work piece in question.
