Puzzle Style Acorn Locks 1/2" Thread
This set includes 4 pieces puzzle style acorn style 1/2" thread chromed wheel locks and 1 key. They fit many newer cars and trucks.
Fitment and specs
- Thread size: 1/2 inch, must match your existing wheel studs
- Puzzle style locking pattern with one matching key included
- Acorn style seat, same as standard acorn lug nuts
- Chromed finish
- Set of 4 locks, one per wheel, plus 1 key
- Fits many newer cars and trucks
Install one lock per wheel in place of a standard lug nut, using the included key. Tighten with a torque wrench to your vehicle's spec, using our torque reference chart as a guide, then re-torque after 50 to 100 miles. Skip the impact gun; hand torquing protects both the key and the lock pattern.
Common questions
What happens if I lose the key?
Each set ships with one key, and the puzzle pattern will not accept a standard socket, so treat the key like a spare tire tool. Keep it in your glove box and hand it to the shop before any tire or brake service.
How do I confirm 1/2 inch is the right thread?
Match it to the lug nuts already on your vehicle. If your current nuts thread onto 1/2 inch studs, these locks will too, and the acorn seat matches the tapered seat used by standard acorn lug nuts.
