Frequently Asked Questions
Will these work with my current wheels, or do I need spline adapters?
These are direct-fit M12 x 1.25 spline lug nuts—if your wheels already have spline sockets, they'll thread straight in. If your wheels have conical or ball seats instead, you'll need the matching seat style, not these.
How tight should I torque these?
Refer to your vehicle's service manual for the correct torque spec—it varies by platform. The integrated lock helps keep them secure once properly seated, but initial torque value matters.
Are these sealed or treated against corrosion?
Aluminum construction is naturally corrosion-resistant, but finish type and any protective coating aren't confirmed—inspect them on arrival and store in a dry environment if not installing immediately.
