Hi group, I am looking for threaded sleeve, with a round OD. Specifically I require .500 round OD, with 3/8 NC thread ID. I have looked at MSC, Small Parts INC, and a host of other places, and unless I have overlooked it, I have struck out. Thanks in advance for any help you can give, ron
Ron, I _think_ I've seen some types of "lamp rod" threaded on the i.d. How long do you need these? I'm wondering if "joiner nuts" for all-thread might work.
thanks for the info so far, I should say that I am looking for 100 of these, so turning the OD on the hex nuts is not too attractive at that quantity. I have been drilling & threading cold rolled round bar, but that gets old quick, too. keep any ideas coming!
Nobody but you is talking about a regular hex nut. We're talking about a COUPLER nut which is much longer. It's used for joining threaded rod sections. I've not followed this thread closely, but it seems to me you want 3/8-16, which coupler nuts are 1-3/4" long. See McMaster Carr part number 93350A100 for specs on grade
2 galvanized coupler nuts, then just go to Home Depot where they sell threaded rod, and right next to it will be a little rack where they have their coupler nuts. They're cheap. 1/2" ones are 99¢ so I'd expect 3/8" ones to be cheaper. Like Jim Rozen says, you can get a piece of allthread (threaded rod), center drill the ends, thread on a jam nut, one or more coupler nuts, and another jam nut, and turn the whole shebang between centers. I'm guessing you could turn them round in less than 30 seconds per part once you got the process dialed in. This has got to be your cheapest way to go. Actually, shortening the coupler nuts to 1-1/2" might take longer than turning them round. Fastest way would be if you can set a stop in your lathe spindle, and set them up in a 3-jaw and face them off in one whack.
