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.

Twist-Resistant Plastic Anchors for Block and Brick

Also known as mungo anchors, these have large fins that prevent rotation. 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. Pull-out strength values are 25% of the ultimate values.
