Can someone supply me with a photo as well as O.D. dimension of the speed nut that attaches the emblem to the fascia.

Thanks

Front emblems I have removed were held on by a single "tin nut" - one of these annoying sheet metal hex nuts used to attach trim pieces.
It cut threads into the plastic post of the emblem when it was installed. Unscrews with a 10mm socket.

This is the only pic I could find.

That is the OEM emblem nut. It is called a PAL nut.

Didn't realize they were shiny. Usually they have something similar to a parkerized or black oxide finish.

I also noticed that they use a wavy flange versus a smooth or flat flange.

These are exactly the things I needed to know.

Now I need to see what I have in stock.

Thanks all

Also found some call them Thread Cutting Nuts.

I believe PAL, speed and thread cutting are all correct.

Although I never did figure out what P A L stood for.

You may have already seen this website but they make reproductions for many cars, or Fierostore has them.

Okay.... Now I'm confused.

Is it the shinny one with the wavy flange or the black one with the flat flange?

So far it appears to be the shiny cad-like plating style. Unless someone else has one that is the black oxide style.

I have about 6 NOS emblems and it appears as though GM never included the attaching nut with the emblem.

GM has always been good at being hit & miss for attachment hardware when it comes to emblems. It kind of sucks when you really need the correct assembly line parts.

Googling says "Palnut" is a brand name, to wit, https://apexfasteners.com/f.../palnutreg-fasteners

For "speed nuts" I always think of these guys



but again, the Google says that the thread-cutting type is also called a "speed nut".

Are you doing like a concourse-quality resto on a Fiero that it has to be perfect? That's epic, but ... wow.

Mine was 100% black oxide. I will try to go into my garage in a little bit and find it and then post some pics.

I could not find mine but here is a picture of the rear GT logo which uses the exact same nut. They are indeed black.


These should be the replacements. As mentioned above by fierosound, they take a 10mm socket/wrench. They also have a wavy flange .

Damn! I completely forgot about "metric".

I have a large assortment of those nuts but I know none of them are metric.

Now I may have to see if I can find the assortment of used hardware I pulled off of past parts cars as I never thought about the rear nameplate having them.

I recently had my front nose off on my 88 GT to be painted and took the below picture before I removed the emblem. The speed nut was lightly rusted as you can see and appeared it would have been shiny new. As stated earlier, I removed it using a 10mm socket.

Awesome shot!!! That is what I was looking for. The condition doesn't tell me what coating it had unless you saw some shiny, un-rusted area but does show me the exact style.

Thanks!

I took the rear fascia off today to do some cleaning and noticed the identical nuts on the nameplate as in your photo. These are obviously black oxide coated but seem to be for a smaller diameter stud than the stud on the front emblem. Are the studs on the rear smaller than the one on the front?
