This is kind of a rhetorical question, but the reason I'm asking is because the new rear wheel brake cylinders I just received from Rock Auto (Dorman brand) have 17/64 hexes on the bleeder screws. I have two sets of tiny wrenches, but neither one has a 17/64. I checked the screws with a micrometer, and that is what they are. 9/32 is too big. 1/4 is too small. 7mm is too big (assuming they'd have the gall to put metric hexes on Mopar parts). All I can say is, WTF?:wack:
 
Never made that I have ever known. It could very well be metric.
 
I seem to remember having to use either a 5.5 mm or 6 mm wrench on parts house bleeders. Reset calipers to metric and re measure
BTW Max Hope to be able to park next to you again at this years mopar alley show.

I've bought wheel cylinders for my Dart that have had metric bleeder screws.

I remember a loose fitting metric wrench (7 mm I think) worked with a rag between.
 
It's either metric or very crappily made SAE hex. This is what we get for outsourcing everything and one more reason why I always rebuild original factory wheel cylinders.
 
6.74mm...WTF? Throw a 6 point 7mm on it and youll be set.
 
Here you go! A 17/64 ignition wrench:

Over the years I've found LOTS of supposedly SAW brass fittings which did not have a fractional sized hex and SHOULD have. We are talking here, about allegedly US brass fittings, such as Everhot, Edleman, etc. These companies should hang their heads in shame.

I'm sure you are correct on the crappy manufacturing tolerances.

If it's for bleeding brakes with a chinese brake cylinder that nothing fits, I'm pretty sure I ran into that and got this 7mm to work:

Sorry guys, I wouldn't advise using a ign. wrench on a brake bleeder. Those wrenches are stamped steel and don't have much strength. They would spread easily and round off the bleeder. They are designed to loosen machine screws. You would be better off using a adjustable wrench.

Where do you get the rebuild parts? I'd do the same, but I don't know where to get the parts.
 
That's why my W/C's are 1968 models:they fit perfect, and the bleeders are 100% SAE.
Up here our government, in their infinite wisdom stuck us with metric a couple of decades ago. I really hate having to have two tool boxes. And now with all the offshore stuff we never know what wrench to grab. And what's with the multitude of oilpan drainplugs? Every car I own now requires a different wrench. Remember the 70's? One wrench would cover almost everything. 1/2x5/8,offset, double box. Now I have to scoot under there with a handfull of wrenches;including the 1/2 x 5/8, plus a 3/4, a 7/8, and of course 13,14,15,and 17mm. And evolutionists tell us we are ever evolving into smarter people.I call B.S.

Seriously? Rock Auto, O'Reilly, AutoZombie, Shlep Boys, Advance.......wherever.
 
FYI I tried a 7 mm box and it just spun. I did break them open with a 7 mm open end held cocked, but that seemed like a good way to strip them. I finally hammered an old 9/32 open end down to 17/64, and that fit. But the tolerances are really crappy -- it fits on some flats but not others. BTW I saved the old cylinders for rebuilding next time.
 
I have some forged Craftsman ignition wrenches that have a good snug fit. Open end on one end, box on the other.

Personally, I prefer to use a box wrench. Less chance of rounding, and it stays in place on the bleeder during the open/close/open/close routine. I always attach a hose to the bleeder nipple, so adjustable wrenches, pliers, etc. just don't fit.

Anyway, I found this place "brakesconnect.com" that has bleeders, washers and other components. I ordered a couple of bleeders -- hopefully I can replace these silly buggers.
 
Dormans usually has drawers of these little fittings, like .18 a piece.
