Park SW-0 Spoke Wrench - 3.23 mm
This professional-quality spoke wrench is sized for spoke nipples with 3.23 mm (0.127 in) wrench flats and built for a lifetime of use.
The SW-0 is part of the standard kit here rather than a catalog line we have never handled. Park Tool design and manufacture it in Minnesota; ProWheelBuilder is an independent wheel builder in Georgia and a Park stockist, not the manufacturer.
What it does
A spoke wrench that fits properly is the cheapest insurance in wheelbuilding. A loose fit rounds the nipple, and a rounded nipple on a tensioned wheel means cutting the spoke out and rebuilding that section.
Which size is this one?
This one is 3.23mm. Park list several sizes because the parts really do differ; using the next size up is how flats get rounded. If you are guessing, measure across the flats first.
What Park say about it
- Pro quality, vinyl coated, nickel-plated steel construction
- 3-sided nipple interface for secure engagement
- Color-coded for easy sizing reference

About this listing
One SW-0, shipped on its own. We do not hold it back waiting on a wheel build.
How we use it at ProWheelBuilder
Our Park range is short on purpose: it is the kit a wheel shop actually needs, chosen from the bench rather than from a price list. Unsure whether the SW-0 fits your parts? Ask first. We will tell you if something else suits it better, even if it is cheaper.
Park Tool has been in Minnesota since 1963, and their published repair procedures are written around their own tools — which is why most shop benches look broadly alike.

Warranty
Park's warranty. Most Park Tool products carry a limited lifetime warranty against defects in material and workmanship. Pumps, stools, torque wrenches, electronic tools, motors and power supplies are covered for one year. Normal wear, misuse and damage from improper use are excluded.
ProWheelBuilder. Our own one-year warranty is a wheel warranty - it covers wheels we build, not tools or accessories. This item is covered by its manufacturer, as set out above.
Full terms are on our Policies & Warranty page.
SW-0 questions
Do you ship tools on their own?
They do. A tool order is packed on its own and does not wait on anything else.
Is this the right one for my wheels?
Tell us what you are working on and we will tell you straight. A spoke wrench has to fit the part exactly; the wrong size does damage rather than work.
Not sure? Text or leave a voicemail on 470-253-0929 or email info@prowheelbuilder.com — you will be talking to the people who build the wheels.
