This is a multi-purpose nut from GM, factory part number 94515133.
It is catalogued under Nuts & Washers > Nuts.
Corrosion at a mounting face is worth cleaning back before fitting anything new, because a part that sits on scale will work loose. Torque figures belong to the fastener and the joint rather than to the part, so the factory procedure is the reference rather than a general rule.
