Will these work with my current wheels, or do I need a different seat type?

These are acorn-style lug nuts with a tapered seat designed for conical wheel mounting holes — the most common type on modern vehicles. Verify your wheels use conical seats before ordering, as some custom wheels may require a different style.

Do I need to tighten these to a specific torque value?

Refer to your vehicle's service manual for the correct torque specification — it varies by manufacturer and wheel type. Use a torque wrench to avoid over-tightening, which can strip threads or damage aluminum.

Can I use these on all four corners, or should I stick to one axle?

With 20 pieces in this set, you can outfit all five wheels (four plus one spare). Installation is straightforward — hand-tighten using the knurled grip, then finish with a wrench or impact gun set to the correct torque.
