I make some use of fully threaded studs for one of ScopeRoller's products. Turning into a threaded hole is a struggle because they don't have a head. Usually fully thread studs are flat on each end. I bought a batch a while back that had a hole for an Allen wrench, which of course greatly simplifies turning these in without damaging the threads.
Can't get a sharp focus this close with a webcam.
Is there a special name for this type of stud with an Allen head end?
UPDATE: The vendor MSC Industrial indicates no special name for it. Disappointed to see that a larger version M8x1.25 that arrived today are conventional.
Sounds like what you are talking about is just a standard setscrew. Longer than normally used for holding a gear or the like but a setscrew all the same.

Would use of a cap-nut simplify installation? I can envision just glueing a cap-nut into an appropriate size driver socket to make a stud-insertion tool.
ReplyDelete"stud allen drive" seems to be the search term that brings some up for me

ReplyDeleteYes it is just a long set screw. Stud Allen drive: thanks.
ReplyDeleteMetric set screw also finds them.
ReplyDeleteSimplest solution: double nut the top end of the stud. Lock them tightly together, then turn the stud down to tight, then break the nuts loose from each other and unthread.
