Matching the thread
Lug nuts clamp a wheel to the hub studs, so the thread decides whether a nut can work at all. A nut with the wrong pitch or diameter can cross-thread the stud, strip the threads or fail to hold the clamp load. Before buying a replacement, look closely at the threads on the studs and compare them with the nut you are removing. Thread engagement should feel smooth when the nut is started by hand.
Wear shows up in a few places. Look for rounded or flattened hex corners, cracks near the base, and threads that feel rough when run on by hand. Replace any nut that spins freely without tightening or that shows damage, and replace nuts in sets so clamping stays even across the wheel.
Re-check torque after the first few drives, since new nuts can settle slightly.
