M12 x 1.5 Extended Grooved Shank Lug Nuts 20pc Set - Aluminum

Will these fit my wheels without spacers or adapters?

These are standard M12 x 1.5 thread lugs. They bolt directly onto any wheel stud with that specification. If your vehicle uses a different pitch or thread size, these won't work — double-check your manual or existing lug nuts before ordering.

Do I need to torque these to a specific spec when installing?

Refer to your vehicle's service manual for the correct torque value — it varies by make and model. The grooved shank won't change that requirement. Use a calibrated torque wrench and tighten in a star pattern for even clamping.

Can I mix these aluminum lug nuts with my stock steel ones?

Technically yes, but it's not recommended. Stick with a matching set — all aluminum or all steel — to keep wheel clamping pressure uniform across all studs and avoid stress concentration on a single nut type.
