What goes first

The drive is the part that turns: a drill chuck, a ratchet, a socket drive, and on a sprinkler the drive that moves the head. Listings name it more often by what it does than by what it is made of.

What the listings say

Thirteen listings name a chuck, a ratchet or a drive, spread across four categories. Three print a torque figure, in newton meters or in inch-pounds.

ISO 1174-1 gives the dimensions of driving squares for hand socket tools, in millimeters. ISO 6789-1 sets requirements and conformance tests for hand torque tools.

NIST Special Publication 811 gives the newton meter as the SI unit of moment of force. Torque in this catalog is printed in newton meters and in inch-pounds, and this site does not convert between them.

Silence is silenceA listing that does not name its drive has told you nothing about it, and nothing about it is implied here.
