Review: High visibility, good fit - Works great on Fuel rims on a 2020 Tundra with Gorilla 6 spline M 14x 1.5 HT3 nuts. Good fit but not too tight. I don’t think it’s impact gun worthy, but it did hold up on several lugs that needed an impact gun. . Great quality. Always keep a spare, otherwise you are stuck on the road with no way to remove your tire. Please, don’t forget to check your spare tire pressure!
Review: A lifesaver for getting my custom rims off - Great quality. We'll made. A lifesaver. No one has this tool to get my rims off, I ordered this and it worked perfectly.

## Features

- 6-SPLINE Lug Nut Socket Key Removal Tool - Replacement for lost six spline tuner keys. Fits small-diameter 6-spline lug nuts common on aftermarket wheels (M12x1.5, M12x1.25, 1/2-20) and 41/64" applications. NOTE: Count your splines first!
- 20.5MM ULTRA-THIN WALL - Engineered with a slim 20.5mm outer diameter to fit the narrowest tuner lug holes without scratching aftermarket wheels. This is thinner than standard 20.8mm competitor tools, ensuring maximum clearance. Also works in place of Large Six Spline Socket Key.
- DUAL HEX DRIVE - Universal head fits both 19mm (3/4") and 21mm (13/16") tire irons and wrenches. No specialized adapters needed during roadside emergencies or shop maintenance.
- COLD FORGED ALLOY STEEL - Heat-treated SCM 435 high tensile steel for high-torque durability. When used properly, this heavy-duty construction prevents the stripping and snapping common in the cast-metal keys included with budget lug nut sets.
- Hand Tools Only! Thin wall is designed for manual breaker bars and torque wrenches. Do not use with impact wrenches; power tools, mismatched sockets, and incorrect spline counts are the leading cause of key failure and cracked sockets. Ensure your socket fits the spline lug nuts snugly and no "slack" prior to applying pressure.

## Questions & Answers

**Q: Can you use this with an impact gun?**
A: We don't recommend to install the item by impact gun, it is best by manual. Please ensure that these are the correct 12x1.5, 12x1.25, 1/2" thread pitch for your vehicle.

If you are not sure if this will work on your lug nuts just check out the pictures and check the measurements on your lugs. And please be sure to read the full Product Description.

-Pauline

**Q: does this fit rock warrior lug nuts ?**
A: Hello Jim. This Socket Key for 6 spline Lug Nuts may fit Rock warrior lug nuts, as long as it has 6-sided spline lug nuts (12x1.5, 12x1.25, 1/2" threading). But this is not something we can guarantee. Before purchasing, please take a close look at the images. Checking your lug nuts and your wheel lug holes to confirm compatibility prior to ordering will ensure that the key will work for you.

-Pauline

**Q: Will this work for a 12 X 1.5 thread?**
A: Unfortunately, this key is not compatible with 12x1.5  lug nuts. This key is only compatible with 7-spline locking lug nuts that fit 14x1.5, 14x2 and 9/16 threads.
We do have a 6 spline key that may fit. Please see ASIN : B01B3KTGL4
Please be sure to read the "Important Notes" section in the listing. If you do have any further questions, please be sure to send us an Amazon message.

**Q: 10 spline socket for Voxx wheel lugs, can anyone tell where to buy one?**
A: We do not carry your required item. Unfortunately we do not know who is selling them. You can try doing a google search, or see if a seller on Amazon has it. I apologize for the inconvenience. Please send us an Amazon message, if in the future you are interested in one of our other items.
