We\u2019ve had good luck with thread cutting screws. Found some 3/8\u201c diameter that worked good with the LFeet and butyl tape. Need to pre drill the perlin.

<span>Self taping fasteners would be the easiest. Doing a nut and bolt would be possible but quite time consuming.

<span>But that is my question. Is a self taping screw enough or does it need to be bolted? </span><br>
