I am seeking information on the mounting bolts for a 1914 Ford roadster dash and tail light
1/ Do I use square nuts without lock washers for the dash to frame brackets?
2/ Do I use square nuts without lock washers for the side light brackets?
3/ Do I use square nuts without lock washers for the tail light bracket?
I am trying to be as authentic as possible. Thank you ahead for your answers
2. Brass plated steel hex nuts I believe 9/16" wrench size with flat washers
I researched those very questions when I restored my '14 runabout several years ago. Here's what I considered original:
1. If you're referring to the 3/8" bolts (2 per side) that fasten the forged dash brackets to the frame, I felt it correct to use hex bolts and hex nuts without lock washers (not invented yet).
3. Yes. use flat washers on both these locations.. I cannot find my copy of 'Ford Methods and the Ford Shops' but I remember reading a 1915 statement from an assembly line manager stating square nuts were used when bolts passed through wood. They were either 1/4" or 5/16" thick.
The dash to frame brackets on a '14 take two 3/8-24 bolts drilled for cotter pins, and use a castellated nut and cotter pin. By 1914, they were most likely using the castle nuts with the rounded bottoms. I agree with Royce on the side light bracket nuts, in fact, it's a little faint, but my bolts for the side light brackets appear to have been brass plated too.
I just wanted to correct your statement about lock washers not being invented yet in 1914. The lock washer was invented Thomas Shaw of Philadelphia, PA and patented on April 28, 1868. The patent number is 77326.
This is a zoom in on a photo of the hardware on a new 1914 touring taken in the Ford executive garage at the Highland Park plant in mid calendar year 1914. As you can see all the dash nuts are brass plated. The cowl lamp nuts are either 9/16" or 19/32 wrench size on the 5/16" carriage bolts.

Royce: That photo is one of my favorites. The detail is fantastic! It must be a pretty early '14 too with the speedometer.
Larry I suspect it is the same car that Ford used for a variety of publicity photos in the beginning of 1914 model year. This is probably the same car:
Notice that the windshield hardware is black painted, except the screws, which are brass plated.
Interesting feature of the coil box... the paint is very flat.
Thank you. What about the bolts for the side lite brackets, they look like they are brass plated also.
Correct, most of the dash hardware was brass plated steel. Exceptions are the speedometer mounting screws and coil box mounting bolts which are raven finish.
The dash board appears to be painted black on this car.
Thank you - again - Royce. I learn something new on this Forum everyday. I now have my work cut out for me. Blessed Thanksgiving to all !!
