dropped and bent one of the threaded rods for my Jorgensen 8” hand screw clamp. Can anyone tell me what the specs of the threaded rod is so that I can replace? Much thanks.

Good opportunity to expand your skillset and learn how to measure threads.

If you need to replace the clamp, I recommend Highland Woodworking Miro-Moose clamps. Virtually the same as Jorgys and equivalent quality. The threaded rod may be difficult to repair or replace.

There are a number of web sites that can help!
If these are the wooden screw clamps, realize that the threads change direction about half way the length!

How bent is bent? I would try to straighten what you have by taking it apart and sandwiching it between some boards and giving it a few whacks, or putting it in a padded vise and putting a larger pipe around it and try to pull/push it back to some semblance of straightness.

I got good and mad and decided to hammer the rod back to shape. The rod was bent so that I couldn’t unscrew it. I was surprised what a few good whacks could do. Thanks for your help guys

BTW it’s called an ‘Acme’ thread (square profile) and you’ll not find it in your local big box.
