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.

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.

Removable-Bolt Anchors for Concrete
Turn the bolt to expand the nut for a secure hold in concrete. These anchors are often used to anchor machinery. Bolts can be removed and reused in the same hole or used in a new hole along with a replacement expander nut (sold separately). To install, thread the nut onto the tapered bolt and insert into a hole. Made from zinc-plated steel, they resist corrosion in wet environments. Pull-out strength and shear strength values are 25% of the ultimate values.

Tamper-Resistant Pin-Drive Anchors for Block and Brick
A tamper-resistant nut prevents unwanted removal of the object you are anchoring. Turn the nut round side up for a domed look or countersink the nut flat side up for a flush surface. To install, hammer the pin to expand the end. When the pin is flush, the anchor is set. Pull-out strength and shear strength values are 25% of the ultimate values.
