Looks to be 3/8-10. 3/8 being the diameter and 10 being the number of threads per inch.
Is it sticking out a little over an inch? I'm counting 11 threads visible.

What's the possibility it's not 3/8-11 I made this mistake before, it turned out to be 3/8-11 When i guessed it at 3/8-10 that cost me , sometime to get what i needed to make it right The only way i new for sure was you try a 3/8-10 pin, then a tap , then the thread gauge lol Also, it's hard to judge anything from one picture, could be the angle that makes the pin look longer.
Hey Op share some measurements info on cue, maybe just length of pin or where the cue came from, maker etc.

If you download the Thread Pitch application to your phone, you can use it to measure the thread pitch. It's accurate enough to determine whether it's 3/8-10 or 3/8-11.
