What length shaft is this? (proper measurement of threaded shafts)

Are threaded shafts measured to the end of the thread or just to the end of the shaft where it transitions into the thread?

Its is a 5/16 shaft with a threaded end. it has a mori slip tip on it. The pics show how i measured it.

i believe this shaft is a mori which come in 66 and 68 according to spear america's website. This seems like a 67 though. Is that possible?

someone please clue me in here. what size shaft is this because i need to order spares.

Re: What length shaft is this? (proper measurement of threaded shafts)

The shaft length is taken from end to end on both threaded and flopper shafts. Most slip tips are about 5 inches long so you would want to get a threaded shaft that is 5 inches shorter than the flopper shaft that you currently have on your gun.
The proper sized shaft for any given gun is debatable. 11 inches of overhang is kinda the standard in either flopper or threaded shaft with the sliptip installed. You can play around with different set ups to find what works best on your gun. Some guns like a little bit shorter shaft overhang and some a little bit longer.

Re: What length shaft is this? (proper measurement of threaded shafts)

Most bigger american guns I've used have a threaded shaft length the same length as the gun. If the mech is near the butt like it should be the rear of the shaft will be about 5-6" from the butt when it seats. That makes the shaft stick out 5-6" and the slip-tip 5" like GR estimated gives you approx. 11".

My Ulusub 65" shot 65" threaded shafts, my Sea Sniper 67" came with 67" threaded shaft.

I think to answer, yes the shaft could very well be 67". Either the site isn't accurate or they are measuring different which would be the first I've heard of anything other than measuring end to end.

If I was made to choose I'd go down to 66". Makes tucking the slip-tip spectra easier a little closer.

Call or e mail the supplier and ask how you measured yours and they should be able to tell exactually what you need.

Thanks for the input everybody. The shaft seems to be a 67" custom built shaft. I ended up choosing a mori 68" to replace it.

It will be slightly less than 11" of overhang (I added an updated picture showing the current overhang on the existing shaft)
