Will these fit my wheel studs?

These are M12 x 1.25 metric threads — they thread directly onto factory metric studs. If your vehicle uses 14mm or SAE studs, these won't fit. Verify your stud size and thread pitch before ordering.

Do I need to use a torque wrench?

Yes. Always torque to your vehicle manufacturer's specification — refer to your service manual or door jamb placard. Don't rely on feel alone, especially with aluminum nuts; over-torquing can strip threads or under-torquing can cause wheel creep.

Can I use these with my impact gun?

The ribbed shank helps grip during hand installation and removal. For impact gun work, use moderate speed and finish tightening by hand with a torque wrench to avoid damaging the nut or stripping studs.
