I was concerned about some of the bad reviews on these screws but I think they were all plain plated screws. These stainless steel screws are great and are more likely to bend than break. Do yourself a favor and pay more for stainless steel. I had to remove a few and literally bend them into an S shape to get them out. They drive great with the camouflage attachment and guidance. You can barely see the holes on the sides for a finished look. I used them on HDPE boards. It worked great.
