expansion fasteners

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.

In conclusion, shear stud bolts are more than just ordinary fasteners; they are integral components of structural engineering. Their effectiveness in resisting shear forces, combined with their ease of installation and cost-effectiveness, makes them a preferred choice in modern construction. As technology advances, so does the sophistication of these bolts, further solidifying their position in ensuring the robustness and longevity of our built environment.
