When competitive racing hits the boiling point, everyone reaches for light-weight items which provide an advantage in and out of the pits. JConcepts has the answer with the introduction of the Fin styled light weight 17mm fine thread wheel nut set. 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 new wheel nut includes a set screw to allow a magnetic wrench such as JC #2891-1 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.
