Review on Self Drilling Toggle Drywall Anchors Screws by David Lesperance

DO NOT CHEAP THEM. Just buy the REAL item at Lowes, Home Depot, Ace Hardware. This is a cheap fake. The self-drilling screw goes "just fine" into the drywall, but the additional anchor screw will not INSERT FULLY. This means that due to the POOR TOLERANCES in this system you will be lucky if 50% of your bolts succeed. In most cases, the secondary screw gets stuck halfway, leaving what you were trying to mount to the wall NOT securely fastened and not securely fastened. We screwed up enough drywall with this POS.
