The structure of the plug allows it to work in 4 directions and guarantees an equal distribution of strength applied to the substrate.
Once inserted in the hole, the lugs and 2 tabs hold the plug in place and prevent it from spinning right after the screw is partielly driven into the hole.
The internal design of the plug guides the screw.
The flange prevents the plug from sliding inside the hole and provides a nice finish to the work carried out.
The smooth part under the flange does not expand, so the working surface is not damaged.
