Impact Action Wrench Drive Size

Extensions and sockets do cause variation of actual torque, but not aware on any action that needs exactly xx ft/lb of precise torque. Honestly, I wish all action wrenches were just 1/2" drive female or take 3/4" socket. I've got 3 or 4 different action wrenches, arc, ai, origin, and a generic 700, and they all use different socket sizes.
 
Extensions and sockets do cause variation of actual torque

That’s actually not true, at least at the torque values that you’d be using on an action. It takes enough torque for the extension or adaptor to actually deflect which is a hell of a lot more than 100ftlbs and still isn’t much loss of torque. There are documented tests on this and I’ve tested it myself.

The only place extensions and adaptors really reduce torque is on impact tools and that’s by nature of how they work which is totally different than hand torque.

I know I'm right on the torque variation with extensions, I turn wrenches for part time living. It also depends on what socket, extension, and length of extension. Cheaper tools and various metals used in those tools will determine as much about variation as torque range. Spot on about impact though, extensions "soften" the shock of an impact gun, negating usefulness. As I said, I'm not aware of any action that doesn't have a fairly broad range(20+ft/lb).

I know you’re wrong. There’s plenty of videos on YouTube that you can watch of people actually testing it.
