A butterfly plastic toggle anchor is essentially a two-part system consisting of a plastic body and a metal toggle. The plastic body, often made from durable materials like nylon or polypropylene, serves as the anchor point, while the toggle acts as a stabilizing mechanism that spreads the load behind the wall. The butterfly shape of the toggle allows it to open up once inserted into the pre-drilled hole, providing a secure grip on the inner surface of the wall.

Another important consideration when using shear studs is their corrosion resistance. Since they are often exposed to the elements, it is essential to choose a material that can withstand prolonged exposure to moisture and other corrosive substances Since they are often exposed to the elements, it is essential to choose a material that can withstand prolonged exposure to moisture and other corrosive substances Since they are often exposed to the elements, it is essential to choose a material that can withstand prolonged exposure to moisture and other corrosive substances Since they are often exposed to the elements, it is essential to choose a material that can withstand prolonged exposure to moisture and other corrosive substances3 4 shear stud. Stainless steel or other corrosion-resistant materials are generally recommended for this purpose.
