Common questions
My current bolts have a rounded ball seat. Will these fit?
No. A conical seat bolt only mates correctly with a wheel machined for a tapered seat, and mixing seat types keeps the bolt from clamping the wheel properly. Match the seat style your wheels require.
Are these strong enough for daily driving?
Yes. They carry a Grade 10.9 rating with enhanced torque tension. Install them at your vehicle's specified torque and check them after the first 50 to 100 miles like any new wheel hardware.
