12mm - 1.50 Box of 100 pcs Sold and shipped to Revain. Used on 2010 and 2018 Ford Focus and 2018 Ford Fusion. Only problem is I have 44 nuts left. LOL, the OEM has a larger base, but the 60% thread range is the same. Works up to about 62 cents each. My mother-in-law just paid €5 at the dealer. Not sure if the nuts are tight because the cap can push in at the end? Does not affect the hex part and the 19mm OEM wrench still fits. It was difficult to remove a few old nuts from 2010 and had to bang on the old socket to loosen it. The new nut has a deeper thread and is slightly longer.
