You realize Tekton's ratchets are the same as Kobalt's? And Harbor Freight's 72T ratchets are also the same mechanism. This is why I laugh when people rag on how bad HF is, but then say Kobalt is much better. It's literally the same ratchet design and/or mechanism (depending on which one you buy). That 72T Taiwan mechanism is used by countless tool companies because it is simple, smooth, strong, and reliable. It's not the strongest ratchet out there (generally only 140% of ASME torque), but that's still good (500 ft-lbs of torque in 1/2 drive).
Sockets from Tekton are also probably either the same thing or made to a comparable standard to Gearwrench's and Kobalt's Taiwan sockets. Husky sockets are Apex China, which is below Kobalt or Gearwrench IMHO. Same as Craftsman China and just not that great. If Husky still has the double detents like Craftsman, those are the absolute worst.
Tekton wrenches are also suspiciously similar to Gearwrench's Taiwan made static wrenches (non ratcheting). Doubt they are too different, if at all (the newer combination sets from Tekton, as of two or three years ago, are Taiwan made, no longer China).
Same thing for the ratcheting wrenches. Tekton's are made in Taiwan and could be made by the same OEM that makes Taiwan Gearwrench, or a comparable Taiwan competitor. The 72T ratcheting wrenches certainly use the same mechanism.
As far as I'm aware, Apex owns no plants in Taiwan. They contract out for much of their Taiwan made stuff, which means it's also being made for other companies unless it is copy righted (120XP). Thus, I would bet good money a fair amount of Tekton and Geawrench is made in the same factory or by another comparable competitor to whatever Apex is using (depending on the item). Apex does own plants in China though (at least 2), but I've never been impressed by the products coming out of those.
Tekton also has their USA pliers and Punches/Chisels going for them. Their USA screwdrivers are long lasting, but I'm not the biggest fan of the non symmetrical grip (they're really comfortable if you can make the turns at only a third of a whole each time so that your hand lines up with the grip properly).
