Tools

Secure window frames and doors in walls where your drilling depth is limited. These anchors have similar strengths to double expansion anchors but only need about 75% of the installation depth. All have a sleeve that expands inside your hole to create a strong grip. The sleeve, commonly called a caulking sleeve, also creates a seal to block out air and moisture. Since the gripping force is distributed along the entire length of these anchors, they won’t crack soft materials like block and brick. They’re also known as caulk-in anchors.

To install, place the anchor into a drilled hole, cone end first. Insert an installation tool (sold separately) into the anchor to expand the sleeve over the cone. Then, position your component, insert a screw or threaded rod, and tighten. All create a permanent female-threaded connection that lets you remove and reinstall a screw or threaded rod. They cannot be used in overhead applications.

Adjustable-Depth Installation Tools—Use the adjustable stop to set anchors at consistent depths.

Quick-Set Installation Tools—For high volume tasks, turn with a power drill to speed up repetitive installations.

Light Duty Anchors for Block and Brick

Ribbed

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.

Ribbed—Soft enough to conform to irregular, out-of-round holes, yet hard enough to hold securely. These anchors expand and distort to fit your hole while ribs add gripping force to prevent twisting. Removing and reinstalling your screw will not lessen the strength.

Anchors for Drywall

The traditional, economical choice for mounting lightweight switches, security cameras, and clocks into drywall. All of these anchors expand against your hole’s walls to reinforce your mounting hole and resist pullout.

Anchors

Conical—Ridges on the body prevent spinning during installation, making it easy to tighten down the screw.

Finned—For a secure hold, two large fins grip holes to prevent twisting better than ridges on the conical anchors. The fins also add tension before tightening the screw, so these anchors won't fall out of overhead holes.

Hammer-In Anchors for Drywall

Tap in like a nail—no need to drill a hole or clean up after installation like other anchors. These anchors have a leg that flips open to grab behind your wall like a talon, making them as strong as toggle bolt anchors. Unlike drilling and toggle bolt anchors, these leave a small slit behind for easier wall repairs.

To install, tap the anchor into your drywall until it’s flush with the surface. Then, thread a tapping screw through your component into the anchor and tighten. You can remove your component by unfastening the screw. However, removing the screw will weaken the strength. To remove the anchor, unfasten the screw to release the leg’s grip. Then, partially reinsert the screw to use it as a handle and gently wiggle the anchor out.

Drilling Anchors for Drywall

Skip having to drill a hole. These anchors save you time and effort by drilling their own holes. Their threads offer a stronger hold than our standard plug anchors to mount light fixtures, bulletin boards, and window blinds. They’re also easier to remove but leave a large hole behind.

To install, screw the anchor into your drywall until it's flush with the surface. Then, thread a tapping screw through your component into the anchor and tighten. You can remove your component by unfastening the screw. However, frequently removing the screw will weaken the strength. To remove the anchor, easily back it out with a screwdriver.

Toggle Anchors for Drywall

The toggle locks in place behind your wall to prevent pullout, while fins stop twisting during installation. Unlike traditional toggle bolt anchors, these require a smaller hole and have a flange that covers the hole once installed. Since the gripping force is spread over the length of the toggle, these anchors create a stronger hold than our plug anchors.

To install, fold the anchor in the middle so the toggle wings touch each other. Insert the anchor into a drilled hole and tap it until it's flush with your drywall. Then, use the included tool to pop the anchor open. Next, thread a tapping screw through your component and tighten for a secure hold. You can repeatedly remove your screw without losing strength or the toggle behind the wall. However, the anchor itself cannot be removed.
