I was just curious when Ford started doing the Metric set up to the SAE set up .

The reason I'm asking is I think it maybe time for me to get a metric socket set up . I have 2 newer Ford's a 01 F 150 and my 07 FOFO .
My old 94 F 150 still uses the SAE and I have never really needed to buy anything yet but this newer stuff has become a pain in the buttocks .[scratch]

What should I be looking for as Range wise ? Like 8mm to ????????

Thank you FF [thumb]

My '93 Escort GT was all metric. Because of that, I received a combo SAE and metric socket set for my birthday back in 1993.

7-26mm is good, that's what I have.

I'd imagine that your 94 Ford does use metric, however Ford is fairly good about using sizes that transfer to SAE. What would be the difference would be in the thread pitch since no metric thread pitch corresponds to an SAE. You can get 1.5 mm to go partially on to a 16 tpi, but not more than a couple of threads before you start crossing.

Anyone who's ever owned an old VW Beetle knows what will transfer and what won't- Porsche put a lot of thought into it apparently.

7= 9/32 Ford does use this size on some screws
8 = 5/16
11= 7/16
13= 1/2 SAE size is slightly tighter, good for nearly rounded bolt heads
16= 5/8
19= 3/4 I have no idea why my 4 way has both these on it
21= 13/16
23= 15/16
