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.

Toggle Anchors for Sheet Metal and Wood Screws

These anchors fit a range of sheet metal and wood screw sizes since they form their own threads when installed. To install, fold the anchor in middle, insert into a hole, and tap flush. Thread a screw through your fixture and into the anchor. Extended length is the overall length of the anchor when folded in the middle.
