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.

As the construction industry evolves, new materials and fasteners are consistently being developed to meet the growing demands of builders, contractors, and homeowners. Among these innovations, black phosphate drywall screws have emerged as a notable choice for professionals seeking durability, efficiency, and aesthetic appeal in their projects.

Moreover, the year 2014 possibly identifies a production standard or innovation milestone relevant to the fastener industry, emphasizing advancements made in that year concerning materials, designs, or manufacturing techniques. This specification could reassure manufacturers and engineers that these screws meet the latest industry standards for quality and performance.
