Questions concerning bolts(fasteners)
Not paintball bolts, but bolts as in threaded fastening objects...
What is it called when a bolt isn't completely threaded throughout the whole bolt? As in the whole bolt has a head then a long non-threaded portion, and at the very end it is threaded?
And also, where could I find bolts like this that could be small enough to, say, screw into a tippmann valve to replace the valve stem to cut off blowback? I have looked around hardware stores and there is nothing small enough, and also online. Unfortunately I don't know the real name for them so my searches are probably sloppy.
