Review on 💪 Maximize Versatility and Strength with Fischer DUOPOWER Universal Anchor Screws by Ryan Brunson

When they are successfully installed, they are great. The problem is hollow walls. There is a very small "ridge" on their outer end and you must use considerable force to tighten the screws. This makes it easy to accidentally push the anchor through the drill hole, making it too wide. I had to order molybdenum bolts to use where it happened. If the anchor does NOT push through you will get a very strong result, but I have found that this happens about 1 in 4 drywall applications. If I hit a hairpin, I can use a screw. If not, I can use a molybdenum screw. I will use them up and not buy them again. If only they had a wider "lip" they would be great.
