69 side reflector install issue -frustrated

[440beep]

How do these 69 side reflectors install? Tried tightening the nut but it just starts spinning and doesn’t tighten.

DadsBee, I followed your thread, but doesn’t help with the obvious I’m missing. Or am I using the wrong nuts? I didn’t see any 69 specific ones.

Well, that’s a “speed nut” that cuts its own threads as you go, and since your studs look brand new (no speed nut threads cut into them yet), I think you need a smaller diameter speed nut

You have the wrong nuts. Those are for 10-24 machine threads.

Yours are a #10 stud
I;ll bet the ones you have are the ones on the left.
You need the ones on the right

I would guess that the reproduction nuts are probably the cause

Any idea what thread the right is? Curious if I can go to hardware store and get what I need?

I’m looking online, and where do I find these please? Layson’s has a bunch listed, but not sure what I’m looking for. Mega Parts doesn’t have them, Classic has a 1/8 flanged acorn thread cutting nut.
