The TOGGLER ALLIGATOR AF8 flanged anchor provides a secure hold in solid and hollow concrete, brick, stone, and drywall, includes #12 x 1-3/4" sheet metal screws, and is made in USA. Once inserted into a 5/16" drilled hole in a wall, ceiling, or floor, the anchor accepts an included screw. The anchor head is flanged for additional stability compared to a flush-mount head when installing into hollow material and has fins that grip the mounting material to prevent spinning when a screw is inserted. When installed within a solid material, the corrosion-resistant polypropylene body expands and elongates to fill and mold to the hole. This helps distribute the force evenly throughout its length to help prevent wall fracture. When installed within a hollow material or a solid material with unexpected cavities, the anchor"s jaws open as a screw is inserted, locking the anchor and screw within the material. If using screws other than those supplied, the anchor accepts a #8 to #14 size screw with a thread length at least equal to the thickness of the item being fastened plus 1-13/16".SpecificationsUltimate Tensile Strength ValuesAnchorDrill DiameterScrew Description1/2" Drywall3,500 psi ConcreteA5/AF53/16"#8 sheet metal screw57 lb.544 lb.A6/AF61/4"#10 sheet metal screw69 lb.675 lb.A8/AF85/16"#12 sheet metal screw85 lb.1,025 lb.A103/8"#14 sheet metal screwN/A1,168 lb.

Anchors provide support through methods such as expansion from within or behind the substrate, or insertion of adhesive compounds into drilled holes.TOGGLER Anchor System manufactures wall anchors and toggle bolts.
