JConcepts 17mm Finnisher Serrated Magnetic Wheel Nuts are ideal for when competitive racing hits the boiling point, and provide an advantage in and out of the pits. These high precision wheel nuts are flanged and knurled for locking security and feature a closed end to protect from dirt and debris build-up in the axle or hub. In addition, the wheel nut includes a set screw to allow a magnetic wrench such as the 17mm Finnisher Magnetic T-Handle Wrench (JCO2891-1) to attract each other for quick changes and stops. 

Completely CNC machined, the large flange and clamping surface area supports the wheel and helps maintain geometry during flex and load. The larger area also provides more footing for the serrated area which provides a more comfortable lock-down. Cutting weight was accomplished by reducing material sections in unneeded areas, in addition, the nut is sliced removing even more bulk and adding a “Fin” like appearance. The closed-end cap features an array of etched logos for authenticity and brand awareness. 

NOTE: It is recommended to add a small amount of CA glue to the set screw and install from the inside of the nut. Position set screw so it touches the magnet inside the wrench and has holding power. Allow the CA on the set screw to cure in that position before use. 

  • Light-weight, World Championship winning DNA

  • Large flange for additional support

JConcepts 17mm Finnisher Serrated Magnetic Wheel Nut (Blue)
I'm not sure what these are actually intended for, but they would not work on my XO-1 hubs. These are machined with a fine thread vs. the coarse thread on the XO-1 hubs. They're beautifully made and finished but would not work for my application. I'm disappointed to say the least. Why this information is not included in the product description just doesn't make sense.
