This is a wrench set, Wright Tool 721, in 12-point, 14 pieces. 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.
Covers a size range in one roll so the job does not stop while you hunt the one size you skipped.
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.
