The spline head is narrower than a standard hex, which is the point: it drops into tuner style wheels with lug holes too tight for a regular socket. Install with the included spline key, torque to your vehicle's spec using the torque reference chart, and re-torque after 50 to 100 miles.
Common questions
Do I need to match the seat type on my wheels?
Yes. Conical, mag, and ball seat hardware is not interchangeable, so confirm the seat your wheels are machined for matches these bolts before ordering. A mismatched seat will not clamp the wheel correctly.
How do I choose the right shank length?
Match the bolts you are replacing. This version runs a 1.25 inch (32mm) shank and 2.43 inches (62mm) overall, and running the wrong length can bottom out or leave too little thread engagement.
