Fitment and specs
- Thread size: 7/16"-20
- Acorn style wheel lock
- Chromed finish
- Set of 4 locks with 1 key
- Fits many newer cars and trucks
Swap one standard lug nut on each wheel for a lock, snug it with the key, then bring it to your vehicle's spec with a torque wrench using our torque reference chart. Re-torque after 50 to 100 miles of driving. The single key fits all four locks, so one tool handles the whole set.
Common questions
Can I install these with an impact gun?
It is better not to. Hammering from an impact gun can chew up the key's engagement pattern and make removal harder later. Run them down by hand with the key and finish with a torque wrench instead.
How do I confirm 7/16"-20 fits my car?
Match it to the thread of your existing lug nuts, which you can find in your owner's manual or by checking a nut you already have. A correct match threads on smoothly by hand; if it binds after a turn or two, the thread is wrong.
