What minimum bearing length is commonly required at the ends of engineered wood floor members unless the manufacturer specifies otherwise?

Engineered floor members typically need on the order of 1-1/2 inches of end bearing on wood or metal (and more on masonry or concrete), following the manufacturer's tables, so the reaction is safely delivered. A 1/2 inch is too little, a flat 4-inch rule is not universal, and hangers still require adequate seat or nailing capacity.
