Confirm your studs are 9/16"-18 before ordering, then start each nut by hand a few turns so you know the threads are clean. Tighten in a star pattern to your vehicle's spec using our torque reference chart, and re-torque after 50 to 100 miles of driving.
Common questions
Can I use these on wheels made for mag or ball seat lug nuts?
No. Acorn lug nuts use a tapered seat, and the seat must match the wheel. Mag seat wheels need a flat washer style nut and ball seat wheels need a rounded seat, so mixing seat types will not clamp the wheel correctly.
How do I know these fit my truck?
Check the thread on one of your current lug nuts or in your owner's manual. This 9/16"-18 size is used on many Chevy and GMC trucks, and the drawing on this page shows the exact dimensions so you can compare against the nuts you are replacing.
