Resin anchors, also known as chemical anchors, are a type of fastener that utilizes a two-part epoxy resin system to securely attach components to concrete surfaces. This system consists of a resin cartridge filled with a mixture of resin and hardener, and a separate bolt or anchor that is inserted into the cartridge. When the bolt is rotated, it mixes the resin and hardener, causing a chemical reaction that rapidly cures the resin and creates a strong bond between the anchor and the concrete.

Butterfly screws, also known as toggle bolts, are a type of fastener that features a pair of wings that fold during installation and expand once they are inside a pre-drilled hole. The design allows for a stronger grip on hollow walls, such as drywall, where regular screws might not provide sufficient anchoring. Butterfly screws are particularly useful for mounting heavier items like televisions, where the risk of falling can be a significant concern.

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.
