Last weekend I patched and mounted shelves in my garage and used exactly 100 of those plastic anchors, zero failed on me. I finally learned to drill the pilot hole a hair smaller than the anchor and tap it flush with a hammer. Anyone else have a count where their prep method finally clicked?
Man, I had the total opposite luck last year. I hung a big shelf in my shed and went through like 12 of those plastic anchors because every single one spun in the hole. Turned out my drill bit was too big. Once I sized down and started tapping them in with a hammer instead of cranking them with the screw, everything held solid. Now I keep the anchor next to the bit and match them up before I even touch the drill.
