What fastener is commonly used with round flexible duct?

Duct tape
Zip ties
Rivets
Self-tapping screws

The correct answer is: Self-tapping screws

Self-tapping screws are commonly used with round flexible duct because they provide a secure and long-lasting connection. They are specifically designed to create their own hole as they are driven into the duct material, making installation easier and more effective. Using self-tapping screws ensures that the duct remains properly sealed and connected, preventing air leakage and improving the overall performance of the HVAC system. On the other hand: - Duct tape is not suitable for securing round flexible duct as it may not provide a lasting and secure connection. - Zip ties are not as effective as self-tapping screws in securing round flexible duct as they may not hold the duct in place securely. - Rivets are not commonly used for connecting round flexible duct as they may not provide the flexibility required for duct installation and maintenance.
