Will these fit my wheel and vehicle?

M12 x 1.5 is a common metric thread size, but you need to verify thread pitch and stud length against your vehicle's specs. The 50mm extended length is designed for wheels requiring deeper reach — test-fit one nut before committing the full set.

Do these need paint or finishing before use?

Pink aluminum will oxidize over time in outdoor storage. If appearance matters long-term, plan to seal or clear-coat them. Out of the box, they're ready to install.

Can I reuse my old studs with these?

Yes. These nuts thread onto existing studs — no modification needed. Just ensure studs are clean and undamaged before installation. Torque to your vehicle manufacturer's specification listed in the service manual.
