Fitment and specs
- Thread: 12x1.25
- Drive style: spline, using the correct spline key socket
- Shank length: 28mm
- Applications are listed in the description above
Because these bolts thread directly into the hub, run each one in by hand first, bring the wheel up flush, and torque to your vehicle's factory specification with the spline key. The torque reference chart lists the figure to use, and a re-torque after 50 to 100 miles keeps everything tight after the wheel beds in.
Common questions
Is spline drive interchangeable with a hex bolt?
The spline pattern needs its matching key socket to tighten and loosen, so keep the key with your tools. The thread and seat still have to match your wheel and hub regardless of drive style.
How do I know the shank length is right?
This bolt has a 28mm shank. Compare it to your current bolts, since too short reduces thread engagement and too long can bottom out in the hub.
