9/32 is correct size for schwinn, works very well!

My Elgins all use a 3/8 x 24 TPI adjuster screw that has a square head on it. I've got a 9/32" socket in my set (came with the set) but it's hex not square. BUT you can turn it around and use the square drive side on the adjuster and put your 9/32" Allen wrench in the hex side.

Out of laziness and lack of decent tools...I use a Crescent wrench and fingers. It's even worked with rusted in tensioner screws with a little penetrating oil. No boogering at all.

I found a few 8 point sockets in some miscellanous socket lots that I've bought here and there. They work good for square nuts.

<DERP!> Why didn't I think of that?!

Doesn’t have to be 9/32”. As long as the socket is 1/4” drive, any size socket will work if you have the corresponding Allen wrench.

I use 12 point sockets all the time at work for square head bolts. I'm not sure of the size but it might worth a try

Although a bit unusual, 8 point sockets are a thing. They are also made for square heads. Yes, I would rather have the Snap-On square socket posted earlier but cheaper things are available.
