stainless steel self threading screws

The incorporated washer, on the other hand, serves multiple purposes. Primarily, it increases the bearing surface, thereby distributing the load from the screw more evenly across the material it's screwed into. This prevents damage to the surface, such as splitting or indentation, which can occur when a screw is tightened without a washer. Additionally, the washer can also help in reducing friction and preventing loosening due to vibration.

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.
