Default Bolt and nut orientation

I have seen so many different ways to install bolts and nuts on specific assemblies that it is not funny.

Granted, there are just two ways to install the bolts and nuts to attach a certain part or assembly to the chassis.

The Standards address some of these applications but not all.

I wonder if Ford had very specific ways of attaching parts or if parts and assembly's were just installed, buttoned up and down the line the chassis went?

I like the aviation practice of heads up or forward.

I will bet that what ever was the fastest and easiest way to do the install was the way it was done.

Agree with Aermotor. Heads up or towards the front looks very professional.

an old aircraft rule... the rule of IDA....... bolts point Inboard, Down, or Aft, unless noted differently in the blueprint

I bet that if clearances didn't dictate how a bolt had to be inserted, that it would have depended on whether the worker was right or left handed on how the bolt faced.

I have taken apart many originals but don't have one in the shop presently
All Ive seen is the head toward the fender and the nut inside the frame.

Not even close. Generally if you look close enough at the earliest print of an item or EIs, it will give direction on how the Engineers wanted it done. Ironically, it often is not on the Assembly Drawing itself, but on one of the part drawings where it will list the fastener by part number and often show on the drawing how the fastener was installed. Other times, it will show in the image on the Assembly Drawing.

For those who feel like it was whatever looked best, remember that Ford left nothing to be guessed at by his worker(s). There was a protocol on every process or procedure down to the way .

Interesting question Pluck ! Personally I have struggled with the lack of information very often !
For instance, the bolts that tie together the upper body side panels to the lower ones ... I put them in with the nut on top. A friend asked me why not the other way around. Looked better,
But I felt doing it as I did was more conveniant ...
What is correct ?

Henk, I am confused. Are you speaking about A-56607/8 Panel (quarter) Assy - outside lower and the A-56605/6 Panel (quarter) Assy - upper RH/LH on a 55A? If so, I'm pretty sure it used an A-20530-S ¼-20 bolt with the head on the bottom and nut on the top.

Correct, a 55A Tudor 1929. RQ upper to lower ! Nuts up, bolts down.

Pffff
