$9 · 6 SPLINE TUNER KEY - 2 AVAILABLE FOR $9 EACH OR $17 FOR BOTH - NEW IN BOX

Spline Drive Key 6 Spline Dual Hex 19mm & 21mm (20.5mm Dia.) I recently learned a couple of things the hard way. The first is when I was swapping over to my winter tires after we had that wonderful dump of snow this past winter. As I was snugging up the last lug nut, I learned that these "tuner keys" are not very strong, and it's easy to over-torque and split the material. I'm just lucky I broke the adapter on the last lug nut of the last tire. So the lesson here is that these tuner keys are really easy to break, and you should always have a spare. The second thing that I learned was that the installation kit that came with my tires from Costco is not a standard size. I ordered two of these tuner keys online, and they didn't fit. Went to Lordco, and they didn't have anything on the shelf that would work. They ordered one in...it also didn't fit. So now I'm waiting for another shop to order in a couple of adapters, and I'm hoping those ones work so I can remove my winter tires finally. So if you have tires that use these "tuner nuts", I highly recommend that you have a spare tuner key. Just imagine being out on a highway at night, you get a flat tire, and your tuner key breaks part way through the process of swapping over to your spare. You get a tow truck to come out, and they don't have a tuner key, so now you need to be towed. You don't want that. I don't want that to happen to you...I'm assuming you don't deserve that. I'm in the area of Dunsmuir Middle School. You can check to see if it (or they) fit before committing. Let me know if you want one or both. ($9 for one, $17 for two)
