Screws worked great for our greenhouse application.

Product worked as expected. We needed the screws to drill our poly carbonate panels in the greenhouse we purchased. It only came with clips on the side, but with the winds we have, needed something more secured. We drilled the sinks into the aluminum framing.

Pros

Great for the price I would order again.

Cons

The zinc #3 point self drilling TEK feature may cut through the roofing material causing a weakened structure, leading to costly repairs and the risk of injury
