Who is the manufacturer? I am going to call your bluff on that one.
I never never ever bluff. The manufacturer is AVK industrial products. The Rep for the industrial side of AVK for automotive fasteners is Tom McGee. I acquired the samples you see in the pictures from Marshall Sales in MI and the salesman was named Brian. AVK does not sell direct, only through distributors.
The standard pack quantity for this part number AVK 3047 is 500 and that's the minimum quantity I can purchase from Marshall. The lot number of that part is 0391192.
AVK is located in Valencia CA on Rye Canyon Road according to the invoice I have in front of me. They shipped me the samples per my request to Marshall Sales.
That particular number is a special fastener engineered for Jeep and is not available through any other method. It is not an off the shelf fastener listed anywhere. I had to jump through several hoops including finding the factory designation for that fastener and then several back and forth sessions with Brian at Marshall while he cleared the sale with AVK.
I gave you the part number, go to AVK's site, get the phone number and call them about it.
What do your nutserts measure not including threads? Mine are a little under 1/8" in grade 8. It is hard to tell from a picture but yours look about the same, only not in grade 8. I do not dispute the fact that Jeep can provide direct OEM replacements, but nutserts are still not unique to Jeep as I stated earlier and any spec grade fasteners will conform.
If you even remotely think that they are remotely the same fastener based on the pics, then we have much larger issues than you thinking you know anything about fasteners.
What are you basing your grade 8 designation off of, the color?
Another issue is cost. 49.20 vs 4.80
Not if you buy them 500 at a time.
