Wheel Fastener: Description and Operation
NOTE:
^
Aluminum wheels must use special bulge-type metric (M-12) lug nuts with enlarged chamfers or distortion of the aluminum lug nut seat will result.
^
All vehicles use metric (M-12) lug nuts. Replacement lug nuts must be of the same type and thread size. All metric (M-12) lug nuts are identified
by the word METRIC stamped on the top surface of the lug nuts.
ANTI-THEFT
Aluminum wheels on vehicles are equipped with anti-theft lug nuts (one per wheel) that are installed during vehicle pre-delivery.
^
The key is attached to the wheel lug nut wrench, stowed with the spare tire.
^
To allow vehicle service in the event the key has been misplaced, a Rotunda Master Service Tool Set 164-R3104 or equivalent is available at most
Ford and Lincoln/Mercury dealer service departments. The lock manufacturer can be contacted at 1-800-669-8788 if a master key set is not
available.
^
The key has a circular keyway that is matched to the female slot in the anti-theft lug nut. When locking wheels are reinstalled, tighten to 115-142
Nm (85-104 ft. lbs.). DO NOT use a power impact wrench on the lug nut key.
