What is the thread size for the seven 32 dash screws? I have one but it does not match anything at the hardware store .....

Thanks ....
 
I think they are 12-24 which most of the hardware stores no longer stock. You'll need to go to one of the specialty suppliers like Roy Nacewicz.
 
If you have a good local hardware store (not one of the "big box" places) they should have one of those little drawers for #12-24 screws and nuts.
 
Tom, this is what Roy offers:

Keep V-8ing and 4-banging!

I have found that #12 fasteners are really difficult to find for quite some time now. I equate #12 with something akin to 3/16", FWIW. Like the guys said above, some really good hardware stores still carry a variety of this obscure size. DD
 
Our local ACE Hardware carries some 12-24 machine screws and nuts still, even some slotted instead of Phillips head. I got my dash screws in one of those roadster interior screw sets. I think I ordered a Phaeton set, too. Not correct sets for my Roadster PU, but the two sets gave me enough to work with. If I remember right, the original screw heads were slightly larger than the repros, and perhaps stainless, not chrome (I was missing a couple). Roy N. will probably have the right ones.
 
In the commercial machine screw market, 12-24 is a "*******" thread these days and in machine screw parlances is a "dog"!!! 3/16 dia machine screw would be your 10/24 & 10/32 variety of machine screws!! Trying to find someone with a head "selection" of 12/24 thread is difficult at best because more and more of my suppliers are not carrying that thread anymore and especially in a slotted variety as "everyone" wants phillips these days.

You are correct! Not sure why I MIS-stated 3/16"......I meant to say akin to 7/32".

And yes, as stated above, my ACE Hardware has a huge selection of fasteners, including #12 stuff. DD
 
I learned early on that a call to Roy solves all these problems, saves a lot of time, money and you get the right stuff. You will waste a lot of time and gas trying to chase down fasteners for these old cars. The thick headed bolts, Odd sizes, SAE threads, odd lengths, special finishes, slotted screw heads, etc almost certainly means you will not actually succeed. Even if you do think you found something, how many times do you get to go back just to get some more 5/16 lockwashers? One of the beauties of Roy's kits is that you get all the right pieces in a bag that is labelled and possibly instructions on where they go. On kits like fender or running board mounting, you do not have to count out 30,40 or 60some pieces of nuts, bolts and washers. Just dump his kit back into a tray and you are ready to go.
Just my opinion
 
Unfortunately
Most bolt & screw companies (like me) are commercial/industrial suppliers...automotive, even though the diameter and threads match, the form of automotive bolts and screws can be way different!! In the industrial world 7/16's & 9/16's are the absolute "WORST" diameters you can have yet in the automotive world they are widely used diameter's, WHY I have no earthly idea??? I'm in the business and a call to Roy is the ticket, easiest, and will be exactly what you need!!!
 
Even if you find a place that has #12 screws, the odds that they will have them with nickel-plated binding heads are zero and anything else looks undersize and out of place on a '32 dash.
 
The Society of Automotive Engineers specifications did have some strange sizes in the early years but at least they finally made standards. There was even a thread that was called National Standard that was in between National Fine and National Course. The only company that I've found that used that spec was Harley Davidson. I guess they wanted you to go to your local dealer to get the hardware since no one else had them. When I was restoring those old bikes, I had to buy the taps & dies but they are pretty much useless other than that.
 
There are also extra fine in addition to standard and fine threads. The model A tilly carbs I used to restore had several extra fine screws.
 
When in doubt, look it up (page A-12-22). They are not #12 binding head screws, but rather are #10-32 x 5/8 binding head screws (Ford part number 350110-S6) for the early dashes with the indented upper section. For the later dashes with the convex upper section they are #10-32x 7/8 (350117-S6). '32 phaetons and roadsters used only the shorter version.
