This is a ratchet, Wright Tool 3426, in 3/8-inch drive, knurled grip. Wright hot-forges its tools from alloy steel at its own Ohio plant rather than buying forgings in, and the working faces are cut to bear on the flats of the fastener rather than the corners.
The drive tool the sockets hang off – tooth count matters most in tight quarters where you get a few degrees of swing.
Wright Tool has hot-forged hand tools in Barberton, Ohio since 1927, and publishes a per-SKU disclosure for the small share of its line that is not US-made.
