I want to connect two parallel, overlapping wooden beams by putting two steel “braces” on each of the ends of the overlapping stretch, so four in total. These braces should look like the one I’ve drawn, with holes for one, two, or more screws on both sides.
The beams rest against a board, so there needs to be room for the heads of the screws, but whether there’s a few millimeters space (like drawn) or several centimeters doesn’t matter. (10 cm are about 4 inches.)
I can buy the beams to fit the braces, so the exact dimensions are not so important. It just can’t be flimsy.
None of the search terms I’ve tried (like “steel bracket,” “steel connector,” or “steel clamp”) has been successful.
