Cognoscenti Weight Bolt specs ?

[tg_vegas]

Anyone got an idea about what the size and pitch are for Cognoscenti weight bolts? I've tried to measure but with the bore for the butt cap being fairly deep, the threads for the weight bolt are too far down inside to use a thread gauge. I guess I could do trial and error at the hardware store but thought I'd ask here first.

Thanks in advance..

It's 3/8x16 thread, bro

Thanks. I finally just did the hardware store trip and tried until I found one. Now the issue is that the threads only go 1-1/2" deep. I just ordered a 4" tap so I can add an ounce and still have enough threads for the butt cap to engage.
