Offering up to twice the strength of double expansion anchors, these US-made anchors expand in four directions for a superior grip in floors, walls, and ceilings. You can even use them to mount heavy machinery with constant motion, such as conveyors and vibrating feeders, because their ridges lock them in place to resist vibration. All of these anchors expand along their full length to distribute the gripping force, so they won’t crack soft materials. You can use them in concrete near edges, corners, or other weak points as an alternative to drop-in anchors.

To install, tap the anchor into a drilled hole. Insert a screw or threaded rod through your machinery and into the anchor. Then, tighten to expand the anchor. All create a permanent female-threaded connection that lets you remove and reinstall a screw or threaded rod.

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.

Pair with large-diameter wood screws, often called lag screws, to secure heavy wood structures like beams and joists to block, brick, and concrete. As you tighten your screw, these anchors expand while their lobes grip the hole’s walls for a strong hold.

To install, tap the anchor into a drilled hole until it’s flush or slightly below the surface. Then, position your structure, insert a lag screw, and tighten. You can remove your lag screw to disassemble or adjust the structure. However, frequently removing the screw will weaken the strength. The anchor itself cannot be removed.

Requiring minimal installation depth, these anchors are best for thin cinder block and hollow core panel walls and ceilings. All expand when fastened to create permanent female-threaded connections that let you remove and reinstall a screw or threaded rod. They fit into smaller holes than toggle anchors for hollow block and brick but are not as strong.

To install, place the anchor into a drilled hole, cone end first. Tap the anchor into the hole until it's flush with the surface. Then, position your component, insert a screw or threaded rod, and tighten.

Drive these tools with a hammer to expand anchors.

The fastest way to install shallow-hole female-threaded anchors. To use, insert the tip of the tool into the anchor and turn the tool with a power drill.

An adjustable stop allows you to set anchors at consistent depths. Use with a hammer.
