Will these work with my factory wheel studs?

These are M12 x 1.5, the standard metric size for most vehicles. Check your stud size before ordering—if your car runs metric threads, these thread on directly without modification.

Do I need a special socket to install them?

You'll need a standard 19mm or 21mm socket depending on your wheel—the acorn cap fits standard sockets. Use your normal lug wrench or impact gun with the appropriate socket size.

Are these all I need to mount my wheels?

These are the lug nuts only. You're securing them to existing studs already on your hubs. If your studs are damaged or missing, you'll need to address that separately before installing wheels.
