Female-Threaded Anchors for Block and Brick
Also known as double expansion anchors, these expand from both sides for full contact and a secure hold. To install, tap into a drilled hole with a hammer and position your fixture. Then, insert a screw or threaded rod and tighten. For maximum expansion, the anchor should protrude slightly above the surface before threading the screw. Pull-out strength and shear strength values are 25% of the ultimate values.

Vibration-Resistant Female-Threaded Anchors for Block and Brick
Often referred to as four-way expansion anchors, these expand in four directions to resist loosening from vibration. To install, tap into a drilled hole with a hammer and position your fixture. Then, insert a screw or threaded rod and tighten. Pull-out strength and shear strength values are 25% of the ultimate values.

Shallow-Hole Female-Threaded Anchors for Block and Brick
Also known as caulk-in anchors, these stay secure when there's not much material to hold. When installed, the cone expands the sleeve to hold it firmly inside the hole. To install, insert the anchor cone end first and use an installation tool to drive the sleeve over the cone. Then, insert a screw or threaded rod and tighten. Pull-out strength and shear strength values are 25% of the ultimate values.

Wood-Screw-Threaded Metal Anchors for Block and Brick
Also known as lag shields, these anchors are designed to be used with large-diameter wood screws. They reinforce the hole and resist stripping. Most diameters are available in two lengths. The shorter lengths reduce drilling time; the longer lengths provide more strength. To install, tap into a drilled hole with a hammer and position your fixture. Then, insert a lag screw and tighten. Install flush or slightly below the surface. Pull-out strength and shear strength values are 25% of the ultimate values.
