Light Duty Anchors for Block and Brick
![]() |
Finned |
These anchors grip the sides of your hole to resist twisting and pullout in block and brick. They’re an economical choice for mounting
lightweight switches, security cameras, and clocks. All are the easiest anchors to install in block and brick but have the lowest strength.
To install, drill a hole slightly deeper than the anchor is long. Next, insert the anchor until it's flush with the surface. Then, thread a tapping screw through your component into the anchor and tighten. Remove your component by unfastening the screw, but the anchor itself cannot be removed.
Finned—For a secure hold, two large fins grip holes in solid surfaces or expand in the cavity of hollow surfaces. The fins also add tension before tightening the screw, so these anchors won't fall out of overhead holes. Removing and reinstalling the screw will weaken the strength.
