Tuner Lug Bolt 12x1.50 Thread 40MM Shank
Fitment and specs
- Thread size: 12x1.50
- Shank length: 40mm
- Seat type: tuner seat
- Threads directly into the hub as a lug bolt
Start each bolt by hand so the threads catch cleanly, then tighten to your vehicle's factory specification with the torque reference chart as your guide. Re-torque after the first 50 to 100 miles so the wheel settles fully against the hub.
Common questions
Is a tuner seat the same as a conical seat?
No. Tuner seat bolts are made for wheels machined for that profile and should not be swapped with conical or ball seat hardware. Confirm the seat shape in your wheel bores first.
How do I check the thread size?
These bolts are 12x1.50. Compare them to your existing lug bolts or the applications shown in the description above before installing.
