2017 Ford Escape Lug Nut Size
When someone asks for the "lug nut size," they can mean two different things: the thread size or the wrench/socket size across the outside of the nut. Ford's 2017 technical specification clearly publishes the thread size and torque. The outer hex can depend on the exact wheel nut design or replacement hardware, so I would not treat a generic socket-size chart as an official Ford specification.
What M12 x 1.5 means
M12 identifies the nominal metric thread diameter. 1.5 is the thread pitch in millimetres. Those dimensions are important when replacing a damaged or missing wheel nut because a nut with the wrong thread should never be forced onto the stud.
What size socket fits the lug nuts?
The most reliable approach is to match the socket to the wheel nuts that are actually installed on your Escape. Original-style capped lug nuts can also change externally if the cap becomes damaged or distorted. Because Ford's owner-manual specification is focused on thread size and torque rather than promising one universal outer hex for every replacement nut, this page does not label a generic socket dimension as an official Ford number.
If a socket suddenly fits differently than it used to, inspect the lug nut rather than forcing a smaller tool onto it.
Lug nut size versus bolt pattern
These numbers answer different questions:
- M12 x 1.5 describes the wheel fastener thread.
- 5 x 108 describes the five wheel mounting holes and the circle they form.
- 100 lb-ft (135 N-m) is Ford's road-wheel lug-nut torque.
If you are comparing replacement wheels rather than fasteners, use the fuller 2017 Ford Escape bolt pattern and wheel specs guide.
Why replacement lug nuts need more than the right thread
Thread size is necessary, but it is not the only fitment detail. The wheel-seat shape, overall dimensions, wheel design and whether the hardware is intended for the wheel all matter. Aftermarket wheels may also use their own approved fasteners.
Ford's technical note says to use Ford-recommended replacement fasteners and gives the torque specification for threads free of dirt and rust. If a stud or lug nut is damaged, cross-threaded or visibly distorted, replacement hardware should be matched properly rather than reused simply because it still threads on.
Why owners search this after tire or wheel work
Lug-nut size often comes up after a tire rotation, wheel change or when buying a spare set of winter wheels. The safest way to keep the information straight is to treat three pages as a set:
- Lug nut size for M12 x 1.5.
- Wheel torque specs for Ford's 100 lb-ft / 135 N-m value and retorque note.
- Bolt pattern and wheel specs for 5 x 108 fitment context.
