I don't think Grainger or McMasters will have those. We need to find a specialty store. I found F-Crimp is one name given to this type or terminal. I also found a site that called it an European Double Crimp. I just started looking, but once I began to use F-Crimp as the keyword search then a plethora of results came up.
I remember BlueMax speaking to me about crimp vs solder. I couldn't remember the problem until I found an explanation that that I copied below and highlighted in red. Also found a
Quality Crimping Handbook in PDF (click the link). Page 30 has interesting pictures of various insulation crimps from Preferred to Marginal quality.
Here is one more web site -
Cycle Terminal - that I found interesting as it is dedicated to OEM style terminals and connectors for Motorsports. It also has a section for
Crimp Tools.

F-crimp is a type of solderless electrical
crimp connection. It is not related to the
F connector common in
RF equipment.
It is sometimes referred to as open-barrel, which is technically a more general term including crimp types such as Weather Pack and Metri Pack.
F-crimp is a more mechanically robust crimp connection compared to the common barrel-crimp type readily available at retail locations (Radio Shack, Home Depot, etc.). It also has an optional second crimp section that crimps to the insulation, providing strain relief. Because of these characteristics, automobiles use F-crimp almost exclusively. F-crimp was devised to eliminate the need for soldered connections - crimping can be preferred to soldering in mass production because it is easier to reproduce reliable connections. These connections, when made with ratcheting application tooling, provide a solderless, "gas-tight" connection. F-crimp connections are never soldered as
application of solder can lead to fracturing of the wire conductor.
The term F-crimp was originally coined by AMP Inc (AMP was a simplification of the company's original name, Aircraft and Marine Products Inc), now Tyco-AMP Electronics, however terminals of this style are currently manufactured by multiple companies. Crimpers are available from multiple sources: manufactures of the connectors typically offer industrial crimp devices for high volume production, and specialty hand tools companies such as
Ideal, Eclipse and Paladin offer dies for hand crimpers. For instance, Ideal die #30-586 and Paladin die #2033 are designed for open barrel / F-crimp connectors. Non-AMP crimpers are available in "ratcheting" ("Certi-Crimp") and non-ratcheting versions, but only ratcheting types are suitable for production applications, with non-ratcheting types being suitable for occasional, or "field" repairs.
