Wrench for prewar rear axle adjusters

[Mack the fork]

I just installed two new repop rear axle adjustment bolts into my ‘40 DX project.

my question:

Is there a specific wrench or special tool to use on them? I don’t want to be “that guy” and immediately default to an adjustable wrench ( with the predictable ham-fisted looking results ).

If someone knows what was used at the Schwinn factory , or in authorized dealer’s shops; please let me know.

Thanks

A 12 point would work if there loose

And an 8 point is made for square heads. No Idea what Schwinn used.

Maybe a 4 sided water key?

Snap on makes 4 sided socket! There's a thread on here all about it!

Wow, thanks everyone. You’ve collectively spared my new adjusters from the indignation of being prematurely bodged.

( bloody things nearly cost a tank of gas !
Therein lies the sickness… )

I use a refrigeration wrench that's for turning valves on and off. I used it on the ship I worked on. It doesn't go on all the way, but works. 1/4" is just under size. Maybe they make a size that fits better.

Take 1/4” socket with 1/4” drive. But the drive end on you adjuster and a 1/4” Allen wrench into the hex end of the socket. An instant adjustment screw tool.

I bought a set of Craftsman ignition wrenches and one of them is the perfect size for heads. Gary
