Request for help finding a 1/4-32 or 1/4-40 screw or threaded rod stock

Depending on how many you are making, you might just grind or mill the outside of a standard nut down to 5/16". Don Young

If you can get by without a hex on the outside, here's what I would do:

Go and grab my can of "T-nuts" for woodworking projects, take a 1/4-20 one and hacksaw or grind off the "head" part.

If you've got a lathe, drill press, or even a 1/4 inch electric drill you could put the T-nut on a 1/4-20 bolt, chuck it up use a file to cut the head down to the largest diameter you can fit in your assembly while it's spinning. then file a couple of parallel flats on it to accept a

Presto!

Hi everyone,

Thanks for all your feedback,

Thanks for the tip on the T-nut Jeff. It may be a viable option, but I have to be able to adjust the nut with a box end wrench due to space limitations. I also need to keep everything as cost effective as possible.

I just started a new thread in the group at the link below, with a link to a drawing that shows the problem in more detail. If I can create a slot in my existing 10-32 screw, I won't need to go with a larger 1/4" OD screw.
