I'm attempting to document the fasteners used on these trucks. It started as an effort to determine the finish color so I can approximate that, but I've realized that it needs to go a bit deeper. Hopefully we can have a document that helps people ID what they have as well as determine the finish for fasteners when they are restoring a truck.

So I've created a spreadsheet to capture the info and need your input on whether I'm getting the right stuff and if it is in a format that will work for you. Here's a start on it and I'd like your input:




Also, I've found what I consider to be a valuable resource in this effort - Ford's 2005 Standard and Utility Parts Catalog. The value is in many forms, one being that we can look fasteners up by the # in the master parts catalog and find out more about them than what's in the MPC in some cases. Further, the parts have a suffix which indicates the finish. For instance the screws that hold the fenders to the radiator support carry a suffix of S43B and that is shown as "Zinc Plate plus chromate - black".




And last, I need your help determining if the Master Parts Catalog is wrong. In the following illustration you can see that the fender is held to the cab with two screws on top and one on the bottom. The top ones decode to being M10x1.5x25mm long and the bottom ones as M8x1.25x28mm long. However, on my two trucks the bottom bolts are the same as the top bolts. So, what are yours? I'm not asking you to remove them, but just check the head size. In my case all three have 13mm heads. Are your bottom bolts the same as the top ones?

 

I believe mine are all 10 mm head size

 

I must have asked the question incorrectly. The ones I'm asking about are shown in the illustration as N606702-S, which go through the fender into the extensions of the cab on top, and N606689-S, which goes through the fender and into the cab at the bottom. Do I need to highlight them and re-post?

 

Here's the drawing with the ones circled:

 

Yeah, that's what I though... been a while since I took that stuff apart but IIRC they're all the same, and it was 8 or10 mm heads for the bolts. Maybe I'm reading your novel too quickly....

 

My top ones are 13mm head, as are the bottom ones. The MPC calls for an M10 up top, which should have a 13mm head, and an M8 at the bottom, which should have an M10 head.

As for a novel, you are suggesting there's too much in there? I should break it down in dribs and ask a question at a time?

 

Mine are 13 mm top and bottom, I checked both fenders. The spring leg to the fender is also 13mm, and the leg to the hood are a 10mm. The hood hinges are 10mm. The front of the fenders have 8mm heads.

 

Great! Just when I feared no one was interested, someone comes through. Thanks!! You've confirmed exactly what my trucks have. What year is your truck?

But, you didn't catch a glaring error in my spreadsheet - how many of each are used at each location. I've since included that in it as well as a source(s) for them, although a source is an issue for some of them and I'm still working on that. In any event, I hadn't posted the updated sheet as I didn't think anyone was interested.

 

I second this.

 

Ok guys, thanks a BUNCH! I thought I was going to have to make a zillion assumptions on this w/o help. But, since three of us have confirmed that both the top and bottom bolts holding the fender to the cab are the same then I'm going to the bank with "the master parts catalog is wrong".

Now for the next conundrum: The master parts catalog shows the screws holding the fender liner to the fender as #55927. When I go to Ford's S&UPC I find that # shown as a standard pan head sheet metal screw - like the one on the left in the picture below. And, to make the plot thicker, I've pulled two different kinds of screws out of these trucks. The vast majority (two 81's & two 82's) have had the screw in the middle, but the 85 had the screw on the right. Can you verify what you have and what year your truck is? All I'm looking for is the head style, which should not require removing any screws.

 

My truck is a 1981 F250, my screws are the ones in the middle.

 

I don't think the one far left is correct for any year.

The ones I often find are like the middle. If the right is a 7mm I've had those before too. I hate them because the heads often corrode enough to not be able to get them out.

I can't tell you what was on what years, I had a 80 and 84 so that doesn't help.

 

Thanks again, guys.

I agree the one on the left is not correct, but it is what the Ford Standard and Utility Parts Catalog says #55927 looks like. Which means there are two possibilities: Either the Master Parts Catalog is wrong or the Standard and Utility Parts Catalog is wrong. I think MPC the most likely culprit since I am finding it is fraught with errors. And, it was only put out for a few years whereas the SP&UPC was used at least through 2004.

So, I'm guessing the 55927 is an error in the MPC, which means it isn't likely we will know the right #. The S&UPC doesn't list a screw that looks to be exactly right - at least that I can find in its 395 pages. But, I found it in the Auveco catalog as #13026, which led me to Fastensome's site:



Hope you agree that's the right one.

 

Thought I'd share what I'm doing on the spreadsheet so have attached a picture thereof. But, you need a bit of explanation.

At the top is the Uses tab of the s/s and it has the various things to be attached to each other, as shown in the Item A and B columns on the left. I've sorted it so that the instances of the same fastener are together.

Then down below is just a copy/paste of the Sources tab, and it looks a mess since the column widths are set for Uses. But, it will suffice to give you the idea. On that tab there is one instance of each fastener with a description thereof as well as the sources I've found for each. However, in the spreadsheet the sources are hot links that take you right to the page from whence you can order the item.

My intent is to make this a living document, meaning that I will update it as I find things - or if you tell me of errors or provide new input. And, I can attach it to a post so anyone can have it. In fact, I'm going to attach this version so you can look at it, play with it, and offer suggestions. It is FAR from done, but I'd love to have input.

 

The one in the middle is most commonly used on my '81 EXCEPT FOR places like, say, maybe the square ends of the fender liner where it's attached to the lower part of the fender (for example).
