I had a screw sheared by a PO in this location under the rear hood seal:
Looks like this:
Top (which I apparently didn't get a photo of) is very broad and flat like the plastic clips you'd otherwise expect there with either a phillips or JIS head and a shoulder the thickness of the plastic trim.
Here is the part diagram where I'd expect to find it, but it's not pictured:
The closest RX-8 I've been able to find in any yards is some 450 miles away. This morning, I took a trip down to a pick and pull yard, and thought I'd be able to find the screw on some other Mazda or even Ford from a similar time frame. Nothing. I found the same screw in a larger size, and the same screw with plastic threads, but not the screw I need.
Is anyone aware of anywhere else this screw might be found on the car, on another car, on any part diagram, have a part number, etc.?

It is not on the diagram, but this is where it would likely be. It goes under the seal, but isn't actually part of it. It actually holds the cowl grille down, but it's not on that diagram either. https://www.jimellismazdaparts.com/s...category=20229
It goes in the holes above 50-019F and above/to the left of 50-019D. This probably should have been the first part diagram I posted... Regardless, it's not present in either.

If you have another screw from the cowl you can bring it to the dealership and see if they can match it.
If you know the size from a common screw you could get a countersunk metric Philip's or hex machine screw and finishing washer unless you're determined to get the OEM screw.
I talked to the parts guy at what seems to be the best dealer option within a reasonable distance of me (hour each way), and he pulled up the same parts diagram... but the screw was there. Turns out it's NLA, and I guess they edit NLA parts out of parts diagrams? Whatever... He read off the part number to me, and it's 9YA1-40-501. Or at least that's what he read off to me... Doesn't show up on anything RX-8 related, but does come up in reference to 95-96 Protege bumpers, 93 (I think it was) RX-7 headlight washer/sun roof, and a non-US market Ford Ranger or Transit. Nowhere could I find a photo of this part to confirm. A few parts dealer websites claim to sell it for between $5-7 (plus twice that shipping), but I have zero faith any of them would actually produce any parts for my money based on recent experience. So... Not great. Best shot would be a Protege if I can find one that old in a yard anywhere around here. With few exceptions, cars get crushed around ten years old...
There's a guy parting out an S2 in the classifieds, and I put a feeler in there. Fingers crossed.
which is a legit site for buying OEM parts from Japan.
I pulled the part no. off the S1 parts diagram. It doesn’t display in the US parts listings. Which is sort of odd; it would usually expect it to display as NLA, but it’s been 10 years since they stopped selling the RX8. The same screw was used on quite a few different Mazda vehicles over the years from what I saw. Regardless, any used 2004 - 2012 RX8 will do for buying a used one too.
.
YES that bolt is genuine Mazda PN 9YA1-40-501 or 9YA140501, in Left Hand Drive RX-8s ONLY, there are 2 one on left and one on right side.
However strange thing is for RX-8 use it was and is ONLY ever sold in Left Hand Drive models??,
I checked RHD and LHD EPC's in Europe/UK and North America that confirms this, plus I checked my S2 RX-8 Right Hand Drive
and it does NOT have this bolt at all, appears black plastic cowl panel is only held on by the weatherstrip locating and push on clips (about 6).
FD RX-7 and Protege models that use exact same bolt...in North America Mazda EPC.
Right Hand Drive EPC All Model use below, FD RX-7, some Protege, B2500 and B2600 (2002).
I don't believe it is NLA, just that the Dealer cant be bothered ordering as EPC list does not indicate NLA, the Dealer would probably have to get MNAO to import from Japan if available, BTW your Mazda Dealer should be able to check Japan stocks live on availability, they can in Australia sure they can in NA.
Series 1 Left Hand Drive RX-8's also use this Bolt 9YA1-40-501.
As do some FDs in Washer/Headlamp Bottle use and in 92 to 1997 PROTEGE, B2500 and B2600 RHD of 2002.
I had no idea that it was even that much more specific... Why would that be the case? I'm sure the holes and bosses are there regardless of market... That's wild.
I dug around a bit, and found the Protege/RX-7 link. I wasn't able to get any more precise on the RX-7 than that it is in either the headlight washers (not a US-spec feature) or sunroof (not a common feature). The Protege use I found was limited to 95/96 or something like that, somewhere in the front bumper. That's a bit old to be in most yards... They'd certainly mostly all have been crushed by now.
Unfortunately, that dealer is the best of a bad lot. I posted in my regional forum looking for the best dealer, and the resounding reply was "none". I did a little test, and called around with a pretty challenging technical question (an actual question I actually needed an answer to) to see which dealer sucked the least. See who picked up the phone (a sad state of affairs that this is even a metric), who would at least give it a good faith effort to try, who would actually put me in touch with someone knowledgable rather than some intermediary messenger telephone game setup, etc. This was the only dealer that even had someone claiming any amount of rotary experience (one dealer even referred me to this one without even trying due to their having a rotary person). It's not a great situation on the whole.
Meanwhile, I more or less gave up on trying to order a new one, and started looking for part outs. I found one not too far from me, and got one. I'm trying to get a few other parts while I'm in there.
Speaking of though, that conversation last night re: finally finding this weird screw uncovered another possible mystery that you, @ASH8, might be able to shed light on. I was changing the oil for the first time on my S2, and noticed one of the bolts holding on what the manual calls the "under cover" (the aluminum tray/plate/cover directly under the engine that is removed to access the oil filter) was wrong. Apparently the service manual guy and the parts diagram guy weren't on speaking terms, because the "under cover" in the parts diagrams all refer to the larger plastic tray/plate/cover under the radiator in front of the "under cover" as named in the service manual I'm interested in. What's more, the "under cover" I'm looking for doesn't actually seem to appear in any parts diagrams I've been able to find! Since I can't find the "under cover" in question, I can't find a part number for my errant bolt. I'm sure it's nothing special, but the closest RX-8 of any vintage in a salvage yard to me is 450 miles away, and the part number would hopefully help me figure out where to look on what other models that might exist nearby.
EDIT: Then I went looking again immediately after posting the above, and found it in the suspension section. There's a logic to it, just not one that's immediately obvious.

there are many things like that. It will drive you crazy until you’ve dealt with it enough to know specifically where to go.
I suppose that’s shy it’s not shown on the S2. You think it’s needed, but most likely not based on the info. They likely just decided to save a few pennies.
I'm getting there. Got the car on the road for the first time post-baselining today (fixing all the known issues, deferred maintenance, etc.). Hopefully the beginning of a long and happy automotive journey!
9YA140501 Bolt is used on RX-7 FD Headlamp Cleaner.
on Protege on the front Bumper.
There is also part number 9YA1-40-502
The 2 two on the end, I used to know all the measurements to the part number, I think end number is mm (millimetres) then there is mm in width, etc etc and thread pitch.
Anyway the 502 is only used in B series Trucks on front bumper with the 9YA1-40-501 and both use the same Nut part number, I think the 502 is a little longer.
The S2 RX-8 Alloy Oil Pan Guard has 7 Bolts of all the same part number 9GGB-00-820.
Well, that solves that mystery... Unfortunately, headlamp cleaners were not a US market thing (unless Mazda gave us one for funzies). So that means a nearly 30 year old Protege bumper, or a B-series truck. I don't know (anything) about Mazda trucks, if I'm honest, other than there was a significant Ford tie up. Fords are WAY more common. Easily 10:1. Depending on the translation of that 1 difference in the part number, that might be the best bet for finding this obscure bit of hardware (had I not found one on a parting out car already). I find it pretty odd that Mazda would have used such a specialized screw in such a mundane way in so few applications... This is my second Mazda, and the first I only owned for 3 months, but I've been around the automotive block a few times. I have never ever seen such a specialized piece of hardware used in such a mundane way in such a limited number of applications. That it's not even present in other markets only compounds the bafflement. It's totally bizarre.
ALL Mazda OEM Part Numbers that starts with a 9 that is a NINE, means it is a standardized part number and NOT model specific.
The 9 can be in Bolts, Nuts or Washers.
Mazda MODEL SPECIFIC Part Numbers Always Start with Letters and Number combination, like..
N3R1-14-302 Oil Filter..... N3R1 is Series 2 RX-8 ONLY.......14 is Oil Pump..........302 is the actual Part Number.
LFG1-13-Z40 Air Filter..... LFG1 is MX-5 (Miata 3 Gen)........13 is Intake system...Z40 is the actual Part Number.
I noticed the number-only part numbers that were common to some nuts/bolts. I figured it was something like that. The breakdown for the remainder of the part number system is gold! Can you flesh that out further? Or is that published somewhere? That seems like a really good rabbit hole for an evening or two's worth of digging for my personal education.
