Frequently Asked Questions
Do these work with my existing wheels?
M12x1.25 is a common size across most aftermarket wheels and many OEM setups. Verify your wheel's lug hole specification before ordering — if your wheels require a different thread pitch or diameter, these won't fit.
What do I tighten these to?
Refer to your vehicle's service manual for the correct torque spec — it varies by model. The adapter socket included is sized for the nut head, but final torque depends on your car's wheel assembly specs.
Are these for just one wheel or a full set?
Twenty lugs covers a full set of four wheels with five lugs each, plus spares. If your car runs six-lug wheels or you want backup pieces, order accordingly.
