  • I have a piece of hardware that I’d like to know the proper name for it. It measures 1/4″ in length, has a 1/4″ smooth bored hole through the center, a 7/16″ hex nut on one end (3/32″ thickness), and fine external threads (I don’t know the pitch) on the opposite end. It appears to be an alignment type fitting but I cannot find another one, nor know what to ask for.

    • sounds like some sort of threaded locating dowel-type pin. it might be threaded to facilitate removal if it were to say be pressed into a blind hole location.
