7/16-28 Bolt or Threaded Rod
 

Does anyone have a good source for 7/16-28 bolts or threaded rod? I've looked at MSC Direct and McMaster, and they don't appear to have any. We need one to go into a very specific mechanism which only mounts with a bolt of that size tapped into the end.

Do you have a manual lathe?

Wouldn't be too crazy to just cut one.

We do... Although no one really seems to know how to use the threading setup.

You might check Fastenal.

No juice.

Try calling them, if you looked on their website. Sometimes they have it somewhere, just not on their site.

Check out youtube for videos of thread cutting using your brand of lathe. Thread cutting is relatively easy once you figure out the basic operations of your lathe.

Could you just buy the die and cut threads on a rod? This thread size is fairly common for panel mounted electrical switches.

I'll second this. I've had success with manually setting a die in a lathe tailstock chuck and turning the main chuck (with the rod in it) by hand.

I'll third it.
Cutting threads on any length over a few inches on very thin rod with a lathe is very tricky, and requires a follower rest and the right tooling. And, even then, without experience, the threads won't be great.

A die will produce excellent threads of the right size on significant lengths of rod at a very low expense and relatively fast speed.

Remember, you don't need the whole length threaded, do you? Just the end...

Buy the die. Trust me.

Amazon lists the die for about 10$. If speed is important take the threaded barrel of a switch and solder it on a rod or bolt. Just make sure you have the treads in the correct spot when tight.

Call Tony at Olander in Sunnyvale

I second this suggestion.
