Spline Drive Tuner Lug Nuts 1/2" Black
6-Spline tuner style black finish lug nuts 1/2"-20 thread size with key. The hex key has both 3/4" and 13/16" head. The lugs are heat treated to achieve extra strength. Our application guide page will answer most of your application fitment questions but do not hesitate to ask us. Add extra keys from accessories on the right, if needed.
Fitment and specs
- Thread size: 1/2"-20
- 6-spline tuner style, driven by the included spline key
- Dual-head key fits standard 3/4" and 13/16" sockets
- Black finish over heat treated construction
Hand-thread every nut first to protect the studs, then run them down with the key and a hand wrench. Torque in a star pattern to your vehicle's spec, listed in our torque reference chart, and re-check torque after 50 to 100 miles. A hand torque wrench is also easier on the black finish than an impact gun.
Common questions
Are all lug nut seats the same?
No. Conical, mag, and ball seats each mate to a different wheel machining, and they are not interchangeable. Match the seat style your wheels are cut for, and ask us with your wheel details if you are unsure which that is.
What happens if I lose the spline key?
Extra keys are available separately, and many buyers order a spare up front. Keep one in the toolbox and one with the vehicle's jack kit so a tire change never has to wait on the key.
