Bohlin uses EB-TY hidden deck fasteners for “their nearly invisible design,” which he says helps maintain “the clean lines of the surrounding architecture.” Made of UV-resistant polypropylene, the 2 3/8-inch-long fasteners have a ½-inch profile that delivers automatic, consistent spacing between boards.
