What needs 11/16" wrench?

1940 Chevy Coupe front bumper nuts are 11/16. I'll agree, I don't use it as much as 9/16 or 1/2in, but they're definitely not useless!

^^^ as well as 40 Chrysler bumper bolt nuts

"Back in the day" Craftsman 1/2" drive socket sets had a 19/32 12-pt socket. Only place I ever used it was on an Allis Chalmers WD (IIRC) .... fit a steering shaft block inside the frame.

In 2011, GM announced production of the 100,000,000th small block (see http://media.gm.com/media/us/en/gm/...news/us/en/2011/Nov/100M/1129_100M_Engin.html). Assuming they have flywheels on them, that's 600,000,000 11/16" headed bolts right there.

I just used one today on the torque converter bolds on a Nailhead SP400

 

Clearly an altered picture both my die grinders are 7/16 & 11/16 to change wheels, bits, discs.

Where's the thread for 15/16 ????

 

Nuts on the head bolts for a banger ford

 

Brass air brake fittings on glad-hands of trucks

 

Old military vehicles seem to be covered in 11/16 bolts and nuts.

 

Yep

 

Steering wheel bolt on a 55 Chevy has 11/16th head.

 

11/16 nuts ( wrench size ) go on 1/2 bolts or studs. ( subtract 3/16 ) 3/16 is your commom denominator. Another example: 9/16 nuts go on 3/8 bolts or studs.
Formula will not work on 12 point nuts.

 

Fuel injector lines on a Ford tractor, plus all the normal stuff like tie rod nuts, shock mounts, 7/16 nuts....

 

7/16 nut mostley .

 

11/32 also crop up on 40's chevy's in random places. dash trim, guage clusters etc.

 

Usually a 1/2 inch bolt will have 3/4 inch head.

 

That's an LS engine not the traditional SBC from 1955.......So it probably metric...Maybe a 11/16 will fit if you hammer the socket on

 

Is this lame thread still going? Whoops I guess I bumped it too.

 

No, GM has not built 100,000,000 (that's 100 MILLION) LS motors. The article refers to the "original" small block-- 265, 283, 302, 305, 307, 327, 350, 400 (did I miss any) variety.

 

This is my first time on this forum. I think I'm going to enjoy it with discussions like this!

 

Obviously the vast majority were not LS engines, but read this from the link

 

So the exception is the rule? GM made 99,999,999 LS motors and one 283. OK.

 

Makes a great hammer, too!

 

11/16, ist that right before 3 quarter
