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.

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.

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.

Female-Threaded Expansion Anchors for Hollow Block and Brick
For narrow holes and small cavities where toggle anchors won't fit. To install, tap the anchor cone first into a drilled hole. Then, insert a screw or threaded rod and tighten. Pull-out strength and shear strength values are 25% of the ultimate values.
