This is a box wrench, Wright Tool 1762, in 12-point, 1 inch. 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.
Full contact on all faces of the fastener, for a bolt torqued down and left to corrode.
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.
