Are the locking nuts integrated or separate from the regular nuts?

The set includes four dedicated locking nuts alongside twelve standard nuts. They use the same M12 x 1.25 thread size and install the same way—just position the locking nut on one wheel stud per wheel for vibration resistance.

Will these work with a standard socket, or do I need special tools?

These fit standard lug nut sockets. Use the socket size that matches your vehicle's original hardware—no special tools needed to install or remove them.

Do I need to replace all my lug nuts or can I mix these with my OEM hardware?

You can use this set to fully replace your original nuts, or mix them in. Just make sure you're using the right thread pitch (M12 x 1.25) for your vehicle—cross-thread risk is real if the spec doesn't match.
