Out of those three Capri offerings, Astro Pneumatic has a couple of contenders which are their ONYX 3/8″ Nano Impact (v2) rated @ 500ft/lb and the 3/8″ Nano Flex-Head Angle Impact rated @ 400ft/lb. wrenches. I don't know who came out with these first, but they're good to have. Nice Capri haul there by the way. I have the Capri super thin 14-Piece wrench set, some hex bit socket sets and the WaveDrive Combination wrench metric set. I'm not disappointed at all.
Astro makes some pretty solid stuff. Everything I’ve gotten from them have been awesome. Some of it isn’t quite all there for millwrighting but that’s fine.
They do make nice stuff. I have their locking universal joints.
