Several readers have asked about the hardware-store solution to the three-way bolt needed for the three-legged folding stool. While I am working on an old-school solution, here is how to accomplish the job with about $3.50 of easy-to-source metal.
Note that this is for 1”-diameter legs. If you bump up to 1-1/8” or 1-1/4”, you will need a longer hex bolt and eye bolt.
One 5/16” x 2-1/2” hex bolt
One 1/4” x 2” eyebolt (if your store carries 5/16”, use that instead)
One 5/16” acorn nut
One 1/4” acorn nut
Two 5/16” washers
One 1/4” washer
When I use this hardware arrangement, I drill 21/64” through-holes in the legs. And I usually coat most of the threads of the eyebolt with some epoxy. This coating prevents the threads from chewing up the hole in the leg.
I’ve had this arrangement in a stool that my 13-year-old daughter has been using daily since last year. So far, so good.

Thank you!
Thanks Chris!
I like economical options, but I don’t think friends let friends buy sub-grade 2 hardware.
Chris, you could use all- threaded rod cut to length in place of the hex headed bolt which would then allow the use of acorn nuts on all 3 bolt ends for a better appearance.

Yes. But the threads will mung the holes even faster. This is from experience.
I was thinking the same as Mike. Could you file/grind the threads down on the part that goes through the leg? Another idea, could you use some sort of sleeve to fit the bolt through to protect the leg? Justin
Chris, I Had not considered that erosion issue. Tandy Leather at one time offered a 3 legged folding stool similar to yours. I made one years ago from their kit and tooled the leather. It had the 3 armed bolt that came with the kit like you would need, don’t know if they still offer it or would have the tri bolt separately. Will check their website.

Thanks for your reply.

Try a google search for “Y wrench” – cut off and thread the ends?
Hey, Chris – could you post a picture of what the original hardware looks/looked like?
