Will these fit my wheel bolt pattern?

M12x1.25 is a common metric size, but verify your wheel's lug hole diameter and your vehicle's stud thread pitch before ordering. L40 extended length suits deeper aftermarket wheel bores—measure your wheel's bore depth to confirm fit.

Do I need a special socket to install these?

Any standard M12 socket works. The open-end design just means the socket separates easily once tight—you'll still use the same wrench or impact gun you'd use on closed-end nuts.

Will the blue finish chip or fade?

Anodized aluminum resists corrosion and UV damage better than bare aluminum, but it's not immune to wear. Expect some dulling from brake dust and road salt over time; re-anodizing is possible but not common for lug nuts.
