Park SW-2 Spoke Wrench - 3.45 mm
This professional-quality spoke wrench is sized for spoke nipples with 3.45 mm (0.136 in) wrench flats and built for a lifetime of use.
The SW-2 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
Most spoke damage we see is wrench damage. The right size grips all the flats at once and turns the nipple instead of polishing it.
Which size is this one?
This is the 3.45mm version. Park make this tool in several sizes and they are not interchangeable: one step too large rounds the fitting off, and on a tensioned wheel that means cutting a spoke out and rebuilding that section. Not sure which you need? Measure across the flats or send us a photo.
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
Sold here as a single tool. Unlike the rims and hubs we list, nothing gets built around it — it ships as it comes.
How we use it at ProWheelBuilder
Everything Park we stock is something we use ourselves. We would rather carry a short list we trust than a long one we have never opened. So if you are buying the SW-2 to build or maintain your own wheels and you are not certain it is right for the job, ask us. We would rather point you at the correct tool than sell you the wrong one twice.
Park's kit is the industry default largely because it is documented. Their repair guides reference these exact tools, and they keep making them.

SW-2 questions
Do you ship tools on their own?
Tools ship alone, usually the same day the order lands.
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.
