So far i have :

10mm : common to interior bolts, eg steering column, and wiring bolts in the engine bay.

17mm : Tranny / Diff fill plugs (front).

24mm : Transfer case and gearbox drain plugs, as well as rear diff drain plug.

additional info appreciated...

 

12mm is also really common; I remember using 10 and 12 almost exclusively during the first cam swap.

 

How about 14mm. I use 14mm when trying to removed the clutch restrictor. I used 14mm while installing downpipe.

 

good info so far guys... !

 

14,17 and 19mm for Shock/Strut Removal.

10-19 should do majority of the car.

 

14mm is also used for the nuts and bolts holding the front seats.

 

10,12,14,17,19 mm will dissasemble just about any Japanese car You get some bigger sizes but its rare (cv joints, drain plugs,etc..)
