Park SW-17 Internal Nipple Spoke Wrench - 5.0 mm Hex
An essential tool for truing wheels with hard-to-reach internal spoke nipples, the SW-17 is sized for 5.0 mm hex-shaped nipples.
The SW-17 sits in the drawer we open every day. 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 5.0mm hex 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.

About this listing
One SW-17, 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. So if you are buying the SW-17 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 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.

SW-17 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.
