Runwell Rack Nuts

When installing a front rack, you may be worried about whether the screws are properly fastened. This hub nut is designed for front rack users and is recommended for those who have such concerns.

RACK NUT is a M9 x 15mm hub nut that eliminates the worry of the nut screw not being fastened deeply when installing a front rack. Because the RACK NUT does not have a washer, it can be tightened with a firm torque even on a shaft that has become shorter due to the installation of a rack.

Comparison with front rack installed

*Shaft length may vary slightly depending on the hub manufacturer.

As you can see in the photo (left or bottom), if you use a standard nut, the inner thread is exposed, which makes it easy for dirt to accumulate and also looks rather unattractive. By shortening the overall length of the rack nut, the thread is hidden by the shaft and is flush with the nut, resulting in a clean look. We also paid attention to the design. We hope you enjoy the distinctive design, which was created by changing the cutting method.

We have repeatedly conducted 24-hour salt spray tests to verify and adopt a surface treatment method that is resistant to rust and does not damage the nut threads.

NOTES

*Even if the product has excellent corrosion resistance, rust will occur if it is left outdoors for a long time or exposed to rain. Please make sure to perform regular maintenance.
