Maybe I misunderstood, but the first page of this thread has several comments about how it's not like home depot where you can walk in and shop. There's other comments like They are like Grainger, you have to have an account, and they won't give you time of day if you walk in off the street. Did I miss something?
According to Fastenal's site they don't have any Armstrong Maxx ratchets at any of their locations close by, so I'm guessing rebuild kits would be a no-go as well. was hoping I had a local Armstrong distributor, but I'm not getting the warm fuzzies
I have yet to walk into a Fastenal that didn't allow walk-in customers or kept the majority of stuff "behind the counter".
5 different Fastenals in the local area that I've been to have the smallest of counters to house a couple of PC/cash register units, and the rest of the floor space is their stock.
You can walk in, wander around and shop.
When Fastenal first opened in this area, they didn't like to break open the 50ct or 100ct bags/boxes of fasteners, which is why I stayed away, and dealt with a couple other businesses that sold smaller counts of stuff.
About a year ago, I needed some fasteners that were apparently in short supply or high demand, and had to travel to 4 different Fastenals to obtain all that I needed - they had no issue at this point about small quantities or opening the larger bags/boxes the two times that required it. Since then, they've been the same - no issue when I needed smaller quantities.
I don't recall seeing any Armstrong tools on the shelf, but have seen Craftsman and GearWrench. The online catalog shows Armstrong (including the Maxx line).
Your best bet would be to stop in and chat with them about it - see if they carry the ratchet you want, or can order it, and if there's any warranty issues, if they will handle them.
