On December 26, 1987 I returned a shirt that I received as a Christmas gift from a well meaning aunt to Wal-Mart. As I did not have the receipt they gave me a store credit for 9 bucks and some change. I scoured the clothing looking for something I might actually wear before giving up and heading over to the hardware section. While looking at the tools I saw a brand that I had not heard of before, Proamerica. There was maybe 5 or 6 small sets available. The one that caught my eye was a set of 5 SAE combination wrenches that came in a gray/clear plastic pouch with red lettering as I recall. This wrench set became my first tool purchase. Several years later when I got a job that required tools these 5 wrenches became part of the tools that I would use until I could replace with "better" tool truck equivalents. I ended up keeping the Proamerica wrenches in my work box with the Matco SAE wrenches I purchased used from Snap On. A few years later while borrowing a wrench a coworker told me that the ProAmerica wrenches were made in Dallas at National Hand Tool. That was over 20 years ago now. Over the years I have read all that I could find on the internet about Proamerica tools, the relationship to KAL and seemingly to Stanley/Proto. That said I have never seen anything concrete as to the true source for Proamerica wrenches. Has anyone ever confirmed that the Proamerica wrenches were made at NHT in Dallas? I understand that they produced Giller and later Thorsen. Could the same tooling have been used to produce the Proamerica wrenches the satin Thorsen wrenches do look similar? I have purchased several of the mil surplus SAE sets and at least one full set of Metric combination wrenches. I find myself using these wrenches over all of my shiny tool truck wrenches unless doing something more delicate given their thicker size.
