Model T Ford Forum: Forum 2014: Hardware finishes
Top of pagePrevious messageNext messageBottom of page Link to this message  By BRENT MIZE on Friday, October 24, 2014 - 07:52 am:

Hi guys,
Is there any type of list that indicates what finishes were used on nuts, bolts, etc on the chassis. I also need references on fender, running board bolts etc.
The Model A guys have a guide to every finish on every nut and bolt on the car.

I am having a lot of fun putting my 27 touring back to as close to new as possible.

The newest judging standards does not have this information included. :-(

Thank you for your help!

Brent,

I would be surprised if most chassis fasteners were anything besides what I was told is a S2 finish.

-S2 was described as Phosphate and Oil. It was a finish that kept the fasteners clean and free running so they could be assembled. This finish has very low corrosion resistance. I doubt if any chassis fasteners were zinc plated.

I haven't come across a complete list for the whole chassis for all years, but Bruce's encyclopedia has a list of finishes used on the improved car engines. I assume that would include the fasteners. I think that chassis nuts and bolts in most places got paint slathered on after they were installed, didn't they? I paint mine before I use them. For chassis I use a satin finish, and glossy for body.

Original Ford bolts with their tall heads aren't as plentiful as I'd like, and in some places I've had to adapt modern ones. That means grinding the modern markings off the heads, stripping off the plating (paint flakes off it), prepping, painting, and baking at 180 - 200.

We nickel plate everything that we want to look like it was cad or zinc plated. No one really knows the difference and it has good corrosion resistance and is pretty tough.

Several parts were nickel plated, but offhand I can't think of anything other than rims and their hardware that was galvanized.

There was nothing cadmium plated on the Model T either. The industrial plating of cadmium falls in the same era as chrome--Starting in the 30s. It needs to be passivized with chromate. It's pretty much considered a contaminate now. In the air/space industries, it's not even allowed any where near titanium alloys or high-strength steels without special application.

Oh, forgot. Steve - I believe Ford did try polished zinc plating on the steering gear housing for a year or two. I suppose it was abandoned because it would quickly turn to something looking like dull silver paint.

To approximate the S2 finish, I paint the bolts/nuts with DuPont DP90 (probably now it's called DP90LF), a satin black epoxy primer. If the assembly was painted after assembly, well the DP is a primer that is compatible under most color coats (there really isn't much 'paint' anymore!). It's very corrosion resistant. As has been noted, silver finish on the average nuts & bolts wasn't done in T period, except for the "dress-up" stuff on the late engines.

I don't know when Ford started using their Raven Finish, but it can be ordered from Eastwood. I've been using it for years, and looks just like original, but you must use the clear spray they include with the kit.
