Park SW-3 Spoke Wrench - 3.96 mm
This professional-quality spoke wrench is sized for spoke nipples with 3.96 mm (0.156 in) wrench flats and built for a lifetime of use.
The SW-3 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
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?
You are looking at the 3.96mm. Sizes in this range are close together and a near-fit is not a fit — it rounds the flats and turns a ten-minute job into a rebuild. Measure the part before ordering, or ask us.
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

How we use it at ProWheelBuilder
We sell the tools we work with. If a tool is on this site, someone here has used it on a customer wheel. If you are not sure the SW-3 is what your job needs, say so before you order — a quick question costs nothing and the wrong tool costs twice.
Park have been making these in Minnesota since 1963 and publish repair documentation for them, which is the practical reason shops standardize on Park: the tool you buy now still matches the instructions in five years.

SW-3 questions
Do you ship tools on their own?
Yes. Tools and accessories ship by themselves; only wheel components get built into wheels here.
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.
