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.

- Enhanced Stability Bracing helps to mitigate lateral movements caused by wind or seismic activity, ensuring that the structural integrity remains intact under challenging conditions.

Conclusion

4. Load Capacity Chemical anchors are rated for both tensile and shear loads. The specifications should clearly state these values, often tested according to specific standards such as ASTM or EN to ensure reliability.
