Had no luck at my local hobby store. They would have to order parts in and even then they wouldn't be to the exact specifications. So I searched and searched online and the only ones I could find where I thought they would be a close enough match were on eBay from China. I've decided to place an order and be patient. I'll check back here in a few months when I get them.

Thanks for all the help! I've discovered a great community on PC Engine FX in the process.

Oh, thanks for rectifying the M vs mm. Perhaps this will yield better results in my searches. I have seen 2.3mm online, perhaps those would be close enough. My caliper was alternating between 2.3 and 2.4 but was more often on 2.4.

I don't why I hadn't thought of measuring them. I guess I was kind of hoping these would somehow be standard. So after much digging and measuring, here's what I figure these are:

Style:
Thread Rolling Screws (or sometimes simply called screws for plastic)
Self Tapping
Flat End
Pan Head

Small screws:
M2-0.75mm X 8mm
Head diameter: 3.2mm

Large screws:
M2.4-0.85mm X 8.5mm
Head diameter: 4.4mm

I'm not too concerned about the head diameter, but finding the right pitch is next to impossible, I don't know if these pitches were common back in 1990 but not anymore. Half the time they're not listed online, I figure if anything is going to damage the plastic, it woukd be getting the wrong pitch. Anyways, I get to go to a hobby shop at lunch today. I'll see if I can track the tamiya ones to compare.

Thanks for all the help!

Doesn't look like I have an Ace Hardware in Ottawa, Canada unfortunately. I have been to other hardware stores but the never have anything this small. I'll try hobby stores as they carry Tamiya products, I hadn't thought of that.

That is awesome. I'll have to figure out which screws these are. I have two different controllers with different screws.

Here's an attemp to post them:

My apologies if this is not the right way to do this.

Hi,

I recently purchased a TurboGrafx 16 system with controllers, I'm really happy with it, it's in a much better shape than I expected based on the auction images. I thought I'd still give it a little cleaning job just to get the last bits out. I always like to clean the controller insides to get those in tip top shape. To my surprise, the screws are all rusted. Not the system ones though, they're so rusted I'm afraid they might break off in a few years when I might want to reopen them again. So I'm now on the hunt to get replacement screws. I don't want to damage the plastic shell's threads so I want to get these exact same ones. My two controllers had different sizes. I don't beleive hardware stores would carry screws this small so I figure I would have to find them online. I don't know how to measure them or what numbers mean when looking at screw specifications  online.

Any help is appreciated, thank you.

Nic

PS: I would love to add photos of the screws in question but the site tells me the upload folder is full. They're about 160KB total...
