What does HF have against 18mm?
« on: October 09, 2019, 12:00:28 AM »
First let me start out by saying Rusty is having too much fun.
 !AOK
Now to the meat of the matter.
 What beancounter decided that an 18mm wrench or socket did not belong in all of their combination sets?
  Was this done on purpose? Or was it a snap decision by a suit that has never turned a wrench in his life?
 I can not remember the last time I needed a 17mm wrench or socket. But on the other hand the times I needed an 18mm wrench or socket have grown on every job.
  Is 18 a bad luck number in the offshore metric culture?
   Your thoughts?

18mm is not a DIN or JIS standard size, itís an American size for a 12mm bolt, times the American standard shank size x 1.5 equals the head size. 12mm x 1.5 = 18mm. That was a GM, Ford or Chrysler, design that all the others followed. Foreign manufacturers have caught on yet, so no 18 mm socket, in import made sets.

All of my Toyotas have either 10mm, 14mm, 17mm or 19mm nuts/bolts on them for the common fasteners.  Like GNAP said, American cars and lt trucks uses 15mm and 18mm along with 19mm and others. Most of my socket sets have 15mm and 18mm in them along with my adjustable wrenches, too. At least the last time I checked.👀

17mm was something I have used many times. My motorcycle had quite a few 17mm.  So HF also does not put a 1/4" ball T handle in their set, which is why I wound up buying the bondhus t handle set.  Who doesn't use a 1/4 ball?
Yea, there decisions on some sets are bizarre.  I have never had to use the  18mm that I can remember.

I've always wondered why a combination wrench set only went up to 17mm.  Why don't they add 19mm to the set?
