1/4 20t One Hole Fins

These Wakeboard fins have two super secure and strong molded in locating studs, with one center 1/4 20 threaded hole, all on the standard 3/4 inch centers. Tracker Wakeboard Fin uses single hole mount because on side impact, a fin mounted with one screw is more likely to spin rather than tip over and rip the screws into the board, or worse rip though the board. You can mount single hole fins by simply drilling a 1/4 inch hole in the middle of your two existing holes.

Please measure the length you need (thickness of your board at the mounting) and add at least 1/2 inch (13mm) extra for thread engagement in the fin.

For our single hole 1/4 20T fins, we recommend allen socket screws using a 2 inch long allen wrench

The single hole fins use “one” 1/4 20T screw per fin.

In most cases, fins have been mounted with either one screw or two screws based on a 3/4 inch (19mm) centers, or 1 1/2 inch (38.1mm) between the locating studs or screws

If you are not sure about the length, please feel free to contact us with the information of thickness of your board. Then we will send you the correct Screw.

NOTE: Screw and Washer are not included with the fin. If you need them, you must order them. The cost is 95 cents per screw/washer.
