Default Speed nuts info requested

Hey all,
A few months ago I put my car into the body shop for major repairs and paint.
I did all the prep work prior such as removing all the emblems and trim and lights, etc.
However, in my haste, I also did not save or catalogue all the various hardware and where they went, knowing that I was going to replace most of it with new.

Now, I have a bunch of old and new pieces and new speednuts and no idea of which goes to what! Not sure how to measure for the correct speednut.
Frankly, not sure how to put them on either.
Twist on? Or push on, twist off?

Any advice appreciated!
Thanks,
Paul

Not sure exaclty what your doing as never messed with cosmetic stuff for my 77 other than re-gluing an emblem back on the fender.

But far as speed nuts, I like the ones that are hex and go on like a nut, those are what came/used for my GMC grill emblem.

Anyways maybe post pics of what your trying to sort out, so others can give you tips.

The rectangular flat thin ones with like 2 opposing clips you press on. The hex shaped ones screw on. As per what goes where. Look in your AIM.I know it takes a bit to find the right pages sometimes, but it's in there.

The hex speed nuts come in a couple-three sizes for our cars. The nut cuts threads in the stud as it's screwed on. Obviously, too large won't cut the threads; too small will be a real struggle to get started on the stud and could, if you force it, snap off the stud. The right size will cut its own threads with just wrench or socket pressure.

Gotcha, so the hex ones do screw on (fairly quickly I'll assume due to "speed" being in the name! )

Still need to find some clip nuts too for stuff like the hood and rear deck vents. Sigh.

Really didn't think this all the way through!

The speed nuts cut very coarse threads – like 3 or 4 threads per inch (?) – so really don't take too many revolutions to fully seat a part, so yep, pretty speedy.

The clip nuts may be of two varieties, as I recall: similar threading to the speed nuts; and a true machine screw nut tack welded on. The screw's threads will dictate which to use where. If the thread is coarse, similar to a drywall or sheet metal screw, then it uses a speed-nut sort of clip. Finer threading, like a bolt, uses the machine nut.

Just FYI, these nuts and clips are likely available from your local auto parts store in the misc. hardware kiosks.
