Good point! I had forgotten about that!!

Straight pipe threads are designated NPSC = National Pipe Straight Coupling.
Also generically referred to as "IPS Threads" or "Iron Straight Threads".


I remember reading a lot about the different brake pad threads years ago, but don't remember enough apparently!!!

There is a 1/4-18 & 3/8-18 specification for NPSC threads. Based on Don's post #6 a supplier may have used the NPSC spec.

There are NPSC nuts, I'm seeing them listed as NPT Straight. Looks like most are brass.
