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.

At its core, the foundation bolt is responsible for several key functions within the firing mechanism. Primarily, it houses the firing pin, which strikes the primer of the cartridge to initiate the firing sequence. Additionally, the bolt itself locks into the chamber when the rifle is fired, containing the pressure created by the igniting gunpowder. This locking mechanism is crucial for the safe and effective operation of the firearm, allowing for the rapid cycling of cartridges and maintaining accuracy during high rates of fire.
