Frequently Asked Questions
Will these lug nuts work with my aftermarket wheel?
Extended acorn design fits most aftermarket wheels, but deep-dish or thin-lip wheels may need clearance verification before purchase. Test-fit one wheel with a sample nut first if bore depth is unconventional.
Do I need to replace all 20 or can I just use the locking nuts?
You can mix and match—use the 4 locking nuts on any wheel and standard nuts on the rest. Many drivers use one locking nut per wheel for balanced security and leave the other three standard nuts in place.
How tight should I torque these?
Refer to your vehicle's service manual for torque spec—it varies by platform. Once torqued to spec, the locking mechanism resists vibration; you don't need to re-torque after the first 50 miles like some aftermarket nuts.
