length. Crescent wrenches (both generic and (R)) are normally
identified by length. 6" and 8" crescent wrenches are commonplace;
150mmm and 200mm ones are less common.
The thread pitch and diameter of the worm drive is different. That
actually matters, since the more expensive adjustables can be rebuilt.
You also can't use a metric crescent on SAE nuts.
