Female-Threaded Toggle Anchors for Hollow Block and Brick
A pivoting toggle bar creates a strong hold. These anchors provide an internally threaded socket connection for threaded rods and bolts. To install, push through a drilled hole; gravity drops the toggle into position. Anchors are removable and reusable. Made from zinc yellow-chromate plated steel, they resist corrosion in wet environments. Pull-out strength values are 25% of the ultimate values.

Adhesive Anchor Screen Tubes for Hollow Block and Brick
Used with adhesive in bricks and hollow blocks, such as cinder blocks, these mesh tubes create a stronger hold for rods and studs than other anchors. To install, first fill tubes with adhesive (sold separately) and press them into a drilled hole. Hold tubes in place by pressing the tab against your block, and insert a rod into them. The rod will push the adhesive out of the mesh screen, forming a plug that keeps the rod in place once the adhesive dries.

High-Strength Toggle Anchors
These high-strength toggle anchors provide an extremely strong hold and stay in position when a bolt is removed. To install, push the toggle through a drilled hole and pull the anchor back toward you until the toggle rests flush against the wall. Then, slide the cap up to the wall and snap off the straps. Next, position your fixture, insert a screw and tighten. For use with machine screws; minimum screw length is the wall and fixture thicknesses plus 1/2". Pull-out strength and shear strength values are 25% of the ultimate values.
Zinc-plated steel toggle anchors resist corrosion in wet environments.
18-8 stainless steel toggle anchors are chemical resistant and may be mildly magnetic.

Tapping Screw Assortments for Concrete, Block, and Brick
Also known as Tapcons, these screws are often used to anchor parts to concrete, block, and brick. Screws have a hex head that allows for a secure grip with a wrench. Drive them into a hole with a hammer drill or socket wrench, or use a specialized installation tool (sold separately). Made from corrosion-resistant-coated steel, they resist corrosion in wet environments. Length is measured from under the head.
