<br>
Self taping fasteners would be the easiest. Doing a nut and bolt would be possible but quite time consuming. <br>
A machine self taping bolt and then adding a nut would be a lot easier than nut and bolt. <br>
<br>
But that is my question. Is a self taping screw enough or does it need to be bolted? <br>
