The exhaust valves were fossilized and crumbled, but I have some Conshelf parts that I was able to substitute.

The test of a true regulator addict: When in doubt, substitute USD Connie parts. :poke: :cool:

Fortunately I have a ton of conshelf spares. Someone gave me a giant segmented toolbox from a Navy Dive team that has tons of parts, orings, diaphragms, c-clips, washers, spacers, seats, plugs, valves, etc. It even had a spare 1st stage in it.
 
Actually, it's a bolt. Screws don't have a nut or threaded socket which this does.

He is correct.
The difference between a screw and a bolt is about its thread and only its thread.

If the fastener's thread is designed to make its own thread when tightened, it is a screw.
If the fastener's thread is designed to be inserted into a pre-threaded mating fastener, it is a bolt.
