Wall Anchors Option for Installing Shelving
Butterfly Bolts Secure Screws
Use Lead Anchors for Cinderblock Walls
Consider Which Equipment to Use
To install the standards, you'll need appropriate wall anchors (Image 1). When installing wall anchors, drill a hole into the drywall and then insert the anchor, which expands to hold the screw securely. There are plastic versions and also metal ones for thicker walls. Butterfly bolts (Image 2) work the same way: drill a hole and insert the bolt with the metal "wings" down; the wings open up inside the hole to hold a large screw securely in place. The only thing with butterfly bolts is they can never be taken out again.
For cinderblock walls you'll need a lead anchor to grip the screws (Image 3). Self-tapping drywall anchors tap directly into the drywall with no predrilling.
