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.

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.

Flanged Plastic Anchors with Screw for Block and Brick

A flange keeps the anchor from being pushed through a hole. Also known as alligator plugs, these anchors split in half when a screw is inserted to reinforce the hole and resist stripping. To install, drill a hole slightly deeper than the anchor is long and insert the anchor until it's flush with the surface. Next, thread a sheet metal or wood screw through your fixture and into the anchor. Length includes the flange. Pull-out strength values are 25% of the ultimate values.

High-Strength Twist-Resistant Plastic Anchors for Block and Brick

A lobed shape makes these anchors more twist and pull-out resistant than other plastic anchors for block and brick. They reinforce the hole and resist stripping. To install, drill a hole slightly deeper than the anchor is long and insert the anchor until it's flush with the surface. Next, thread a sheet metal or wood screw through your fixture and into the anchor. To determine screw length, add the anchor length to the fixture thickness and choose a screw longer than this.

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. Each diameter is available in two lengths. The shorter length reduces drilling time; the longer length provides 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.
