Question: 1 / 400

Which fasteners are typically used with sheet metal square and rectangular duct?

A. X fasteners and hooks

B. Latches and clamps

C. "S" fasteners (slips) and drive clips

"S" fasteners (slips) and drive clips are typically used with sheet metal square and rectangular ducts because they provide a secure and appropriate method of fastening the ductwork together. These fasteners allow for easy assembly and disassembly when needed for maintenance or repairs. Unlike screws and nails which may not provide as secure a connection or may cause damage to the ductwork and are not as practical for this application. Latches and clamps are used in different HVAC components and systems but are not typically used with sheet metal ducts for joining them together. X fasteners and hooks are not standard fasteners commonly used for sheet metal ductwork installation.
