Toggler® Hollow Wall Anchors These Toggler® Anchors provide maximum, reliable holding power in drywall, hollow, or plaster walls. They protect the wall from spalling and breakthrough. Perfect blend of strength and durability in termperatures from -20° to 212° F (-30° to 100° C). They are extremely versatile, using any diameter and type of screw #6 - #14, and only requiring a very small diameter hole. These anchors pre-install without a screw and you can make a hole in the wall with your screwdriver (requiring only a 5/16" diameter hole), providing for the fastest installation. Colorless and translucent, they blend into wall color and texture. Also, these Toggler® Anchors are non-conductive and non-magnetic. They are rust-proof in use with stainless steel or brass screws in any corrosive environment.
