I have these three bolts that I came across. I'm not sure if they belong to my car or not (SJ Oct 64 build). All three are 9/16 head size. Not sure of the one on the end is the coil bracket bolt or not. Any ideas?

Bottom two are too long for coil bolt and serrated lock washer typically not for coil application ether.
-
Does your car have a/c? The bottom 2 look like compressor mounting bolts.
-
It does have AC. Would they be the two that hold it on the side of the dog ear or 2 of the 4 on the bottom of the bracket? The AMK bolts I ordered look nothing like these..
-
The side bolts would be a bit longer, but typically have the tooth washer also. These look like 2 of the 4 bolts that mount the compressor to the iron bracket.
-
A size - diameter, threads per inch and length would be useful. A picture is worth a thousand words, except for perspective.

Does this help?
-
Are they 7/16 or 1/2 dia? The size hex wrench to tighten would be a help.

I believe he indicated in his first post that they were 9/16 hex head.

I'm going through this with our car right now, coincidently enough. Your top bolt with the 'R' in the head marking is your coil bracket to intake bolt. The other two bolts with the serrated, external tooth washers are as Charles states - two of the four bolts that mount the compressor to the bracket from underneath. He's right about the dog leg bracket bolts that screw into the compressor from the left side too (front of your car looking at it). Those would be the same head marking (as your bottom two in your photo) but with a flange head, external tooth washer, as the others, only longer. Found them to be the same thread size and length as the two starter bolts, just different washers and head markings, but consistent with that flange head configuration.
Hope this helps.

Also, if you have Bob Mannel's book or access to it as a reference, on page: 6-48 6K25, photo plate 'C', the bolt on the left is the dog leg bracket bolt that I have in ours (integrated serrated washer type). The bolt on the right, same photo, is what came along and replaced it, later in the model year(s).
-
Checked in the garage after I wrote this morning and left for work, dog leg bracket bolts are 'not' the same length as the starter bolts (V8). Starter bolts are slightly shorter. Same thread but also have 1/2" head, rather than the 9/16" discussed here already (and verified as well). I need to wake up a little more before writing me thinks... :-[
-
Your top bolt with the 'R' in the head marking is your coil bracket to intake bolt.
Quite possible. That bolt, p/n 43265-S8 (3/8-16X3/4 HH, splt lkw) was used for the coil bracket to the manifold for 64 and 66.
The other two bolts with the serrated, external tooth washers are as Charles states - two of the four bolts that mount the compressor to the bracket from underneath.
True. These are 42774-S8 (3/8-16X7/8 HH, ext lkw) were used to mount the compressor.
I believe he indicated in his first post that they were 9/16 hex head.
Thanks Bob.

If you had provided actual dimensions - diameter, thread pitch, length, the information would have been easier to retrieve and post.

Thanks for the information.

I for one am always impressed in the time you take to look up the hardware and grateful for you doing so.

I have already found the spreadsheets very useful, and I am only working on but 1 car at this time.
-
I am too Bob. Well said.
Jim, you definitely set an admirable standard. Always so impressed. I'm terrible with bolt sizes, threads in particular, and you just seem to be able to have that output available and practically IMMEDIATE! I have an old AMK book (think it's 2005) and it's a pretty pathetic sight, I would imagine, seeing me at my computer, trying to reconcile differences and figure these fasteners out. My wife thinks its 'cute', but I remain quietly frustrated most of the time...
-
So were these bolts with these head markings specific to San Jose only at this time period or also at Dearborn? Unfortunate these are not offered by AMK with these markings.
-
Will be interesting to hear what others have to say. My experience over the years has been only San Jose cars, limited also to 64.5-67's. The last time I ordered direct from AMK was quite awhile back, and even then, the compressor mounting bolts I received were not quite the same as original, as we're referencing in this thread. I'm missing one of the "correct" dog leg/lateral bracket bolts going in from the side, so it bugs me that I'm getting by with similar for now.

The AMK stuff is changing all of the time as supplies run out of old stock . You never know until a order comes in to see what next is on the "different" list.

Thanks guys. Check out the revised spreadsheets and the new spreadsheet by size.

That's the only style I have seen, but I have not paid attention to any differences in assembly plants.

+2, thanks!

The odd tubular brace bolts appear to differ at times (sorry don't have anything from other plants related to this detail). Washer makes this assemble stand out
Top three are 66 San Jose example - sorry they are not close enough to make out the head markings

This is an example from 65 San Jose where the head marking is different

Those are great shots Jeff. That photo library you have put together delivers, as always. Unbelievable that you have (and actually know & remember) what you have to resource. It inspired me to get home from work and use some available daylight up here to add what is on our car. Preface this by saying it was a quick photo shoot, logo's are upside down and the engine is undergoing a leak-sealing campaign, so everything external to the heads and block is either off the motor or soon will be. First shot is an overall, starting with the coil bracket bolt on the left, bolt attaching the rear compressor brace bar to the intake, lone lateral (dog leg) bolt that I have currently, then the two AMK replacements for same on the right, along with some serrated, external tooth washers added. The compressor tag bolt is the same as your '65 example and as far as I know, is original on our car (I've had it now for 28 yrs). Not surprised to see this however, as there has been some other fasteners scattered around the engine compartment (star washer/disc washer mix), along with a '65 console end cap for the A/C provision. The serrated washers definitely do stand out, as you mention.
The logo's have an 'EL' on both the 2nd and 3rd from the left, and if you look closely at #3, there's an additional 'H' inside the 'L'. I'd never seen that before tonight.

So I was at my friend's shop today looking through his Eaton pumps and decided to go through his bolt collection and found some additional AC compressor bolts that hold the unit to the iron plate. Most have the EL logo but found one or two that have an R in the middle. Didn't find the longer ones yet that go to the dog ear but might go back Monday after work and look again.
-
The R ones might be fuel pump bolts.
-
In the Library Section of this forum, you will find a Hardware Spreadsheet that is sorted by Size/Dimension. It has about 9300 entries. If you do some basic measurements of bolts for example, diameter, threads per inch and length you may get lucky and determine what the bolt you have in your hand goes to, you know - the one that you found under the rear axle that doesn't seem to have a home. Same identification concept works for nuts and washers. I use it all the time (and I created it).

Lance,
You said the second one from the left attached the brace bar to the intake, is that 9/16 head because mine is 1/2 inch (42789-S2) and the 9/16 won't fit through the back hole and the thread size is way too big...
-
Chris,
Yes, 1/2" head on the rear brace bolt. Sorry about that. Has the ELH head too.
-
Should have also mentioned that Charles is correct: "R" on the fuel pump bolt heads is what I have as well.
-

This was mine in the back, different head marking, not sure if it is original or not
-
I've seen that head marking before. It may have been on some AMK bolts, maybe fuel pump bolts or it could have been license plate screws. Cannot be certain and I have no idea about originality or when used if they aren't. Have an older AMK catalog, 2005, that has a page in front with various logos (the ELH is there), but that marking is not present. Hopefully, someone else can weigh in with more knowledge.
-
There are numerous references on Corvette & other Chevy sites referring to the "F" logo as belonging to Falcon Forge. I haven't been able to find any proof of that. And no, I don't hang out on off-brand forums :o
I've seen them in various places on Mustangs and Torinos. Most recently is a set from my 390GT donor engine. All four oil filter adapter bolts are the "flying F" logo. From examining the washer indentations on the adapter, there is only one set of marks visible, which leaves me fairly certain the adapter had never been off the engine until I removed it. Engine was built December 67.
Has anyone started a list of markings commonly found on Mustang fasteners? It would be a monumental task to match them up with typical locations, I don't know if that could ever be accomplished. But a list of general timeframe might be helpful.

That style marking is usually found on the distributor hold-down clamp bolt. Seems like I remember one other place I've found them, maybe the bigger front/rear oil pan bolts on a small-block V8?

You'ld have to factor in (document) assembly plant and time period also.
Projects like this always start with one person and allot of time ;) Of course with such a project you would need to travel or have input from everywhere since most people can't get this sort of access to cars and parts from all the plants and at least examples from every month of production.
But no I don't know anyone that has tried to do a complete guide. A few have done limited studies As always we tend to focus on one details and ignore or don't focus on another even though they are related many times.

Some more input while we are on the subject but that style "F" flying F or cursive F is also seen very often on SB distributor hold downs 65-67 SJ ,not so sure how consistant after that .
-
Yep, you're right on the money Bob. Just confirmed my distributor hold-down bolt is the "Flying F" inside a circle. You're good! At least I can confirm where I've seen it before...
-
Found this in a DOD listing of fastener markings. The "F" logo was (is?) used by Ferndale Fastener, which is/was a division of Ring Screw Works.
