[time-nuts] 1" 14 tpi UNS die

Tue Jul 7 14:23:42 UTC 2009

I think it is also known as 3/4" NPT for a pipe with a nominal OD of 1.05"

This is the standard Marine antenna mount I believe.

the specification for the thread from.

Pipe has O.D. of 1".

Ok, I will try this from a different angle.

1" - 14TPI UNS thread like you described are very rare outside of the large
machine industry.  They are used for things like bolts on tractors.  I have
a pretty big doubt that it has any application in a GPS antenna.

US pipe thread in the sizes 1/2", 3/4", and 1" are 14TPI, they are not "1.0
inch" in any dimension, however.

It is pretty common to use standard pipe fittings in antenna work.

So how did you arrive at needing a 1"-14TPI UNS die?
