Which fastener provides greater holding power for moving scenery?

The fastener that offers greater holding power for moving scenery is the drywall screw. Drywall screws have a sharp point that allows them to penetrate materials easily, and their coarse threads provide excellent grip in wood, which is often used in set construction. This design helps to secure scenery components effectively, reducing the risk of loosening during movement or handling.

In contrast, carriage bolts, while strong for certain applications, require a pre-drilled hole and do not offer the same versatility and ease of installation as drywall screws for quickly assembling and disassembling scenery. C-clamps are useful for temporary holds but do not provide a permanent solution, and nails, although easy to use, often do not provide sufficient holding power for scenery that is intended to be moved frequently.
