The nylon head also offers a certain level of vibration resistance, ensuring that once the screw is secured, it remains firmly in place. Moreover, the head's low friction coefficient allows for easier turning and tightening, reducing the effort required during installation.

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.
