Oversized spoke nipple/tool question

I am working on donated bikes for unsheltered people. I recently got a cheap Chinese generic cruiser in and don't have a spoke wrench that works for it. The spoke itself measures 2.64mm which I understand is 12 gauge. The nipples (which are admittedly rusty) seem to measure between 4.0 to 4.2 mm. Has anyone been faced with this size nipple? I want to buy a Park wrench to fit, they have one (SW-3) that shows 3.95 to 4mm. They have another (sw14.5) that seems to be dedicated to shimano 4.3 nipples. I feel like this is too large and will end up stripping the nipples. Thanks for the help!

Does a 4mm open end wrench fit well? For a gauge.
A dose of penetrating oil and that may work.

just use a 4" adjustable wrench.... unless you expect to see that bike frequently.

also... motorcycle outlets should have a spoke wrench in the correct size... i still have my step-slotted M/C Disc style spoke wrench, and the Dog bone one that i used to build about 50 M/C wheels...

Moose Racing makes a nice one... the Moose is cool.... 4 to 7 mm, three sizes per end, IIRC... i taped over the sizes i WASN'T using at the time

i'd just go with the small adj., wrench.

Alas: My wrenches only go down to 6mm. I am up for buying the proper tool as I get a fair number of these cruisers donated. I typically don't fool with truing the wheels as they mostly just have coaster brakes so being out of true isn't the end of the world. I just got a truing stand and had some spare time so I thought I would practice on these.

or an old school adjustable spoke wrench like this (red arrow).

they can be cranked down tite on an off size spoke. A little slower to use.

Can be found on ebay. for small beer.

by the way the round spoke wrench on the right is a Campagnolo, pretty rare

I dare say that Park isn't always the first choice for rusty POS bikes. Due to the corrosion, your nipples may require several different sized wrenches, or a multi-wrench or adjustable wrench.

Probably best to go with the multi-wrench that others have posted above. Park used to make a yellow spoke wrench, probably the sw-4 gap in the spoke wrench types since it was bigger than the SW-3 blue wrench. A LBS I was building bikes for brought in some cheap cruisers during the pandemic when they couldn't get anything else and it was also using this size spoke nipple, I think it was the first time I ever used that tool, and the spokes looked like something from an old garden cart. The techs were just using round multi sized wrenches too.
