Need to use Wood screws #6 size. 1 5/8" .
Pre drill and counter sink drillholes to avoid splitting wood. Need clamps to hold in place while drilling and screwing holes. Low torque or hand screw slowly. Clamp Screw front brace and verify alignment before you screw in place. Expensive for not much wood and wine will rest too close to floor unless you raise it up by at least a 2 x 4, (3 1/2").
