Use a snug 17mm six-point socket rather than an impact gun, since a loose or worn socket is what usually marks up a black finish. Hand start each bolt, tighten in a star pattern, and set final torque to your vehicle's spec with our torque reference chart. Re-torque after 50 to 100 miles.
Common questions
Do these work with ball seat wheels?
No. These are conical seat bolts, and conical, ball, and mag seats are not interchangeable. The bolt seat must match the machining in the wheel's bolt hole, so check for a straight taper rather than a rounded pocket before ordering.
What does Grade 10.9 mean?
It is a metric strength class for hardened steel fasteners. These bolts carry that rating with enhanced torque tension, so they are built for the repeated clamping loads wheel hardware takes, not just for looks.
