Maybe you already know this, but "5/16-14" means 5/16" in diameter and 14 threads per inch. Any of these dimensions (or even the shape of each thread) can be slightly off and you'll get that "tight" feeling.Bluesteel said:Got a new toy today, and thought the pin was a 5/16 x 14, however, my other shafts will not fit. Was hoping someone could tell what it is from the picture, or let me know how to tell myself.
Thanks for any help you can give.
