The installation of resin anchors involves several steps to guarantee optimal performance. First, a suitable hole is drilled into the concrete using a hammer drill. The diameter and depth of the hole must correspond to the specifications of the resin anchor. After cleaning the hole of dust and debris, the two-part resin is mixed and injected into the hole. The anchor rod is then inserted before the resin starts curing, ensuring a strong bond as the resin hardens.

The process begins with drilling a hole in the drywall to accommodate the bolt's anchor. The butterfly bolt consists of two main parts the bolt itself and the spring-loaded wings. When inserted into the pre-drilled hole, the wings collapse, allowing the bolt to pass through the drywall. Once the bolt is pushed through and the nut is tightened from the front side, the wings expand against the inner surface of the drywall, creating a secure anchor point. This design ensures that the bolt not only holds the weight of the mounted object but also withstands any pull-out forces.
