Place and Fasten Tread

What happens here

With the stair tread fully assembled and reinforced, carry it to the stair stringers. Carefully place the tread onto the prepared stringers, ensuring it is properly aligned and flush with the surrounding structure. While not explicitly shown, the 'hidden fasteners' context implies that the tread is then secured to the stringers from the underside or from the back, preventing any visible screws or nail heads on the walking surface. This typically involves specialized hidden deck clips, angle brackets, or screws driven up through the stringers into the tread.

Goal: Securely install the assembled stair tread onto the stair stringers using hidden fastening methods.
