A duplex nail is primarily used for temporarily securing two pieces of wood together. Its design, featuring two heads, allows for easy removal after the temporary construction is complete.
Purpose of a Duplex Nail
Duplex nails, also known as double-headed nails or scaffolding nails, serve a specific purpose in construction and woodworking:
- Temporary Fastening: They are ideal for situations where a strong but temporary hold is required.
- Easy Removal: The double head design allows for easy prying out of the nail without damaging the surrounding wood.
How it Works
The key feature of a duplex nail is its two heads. You drive the nail into the wood until the lower head is flush. The upper head remains exposed, providing a leverage point for a hammer or nail puller to easily remove the nail later.
Common Applications
Duplex nails are commonly used in:
- Scaffolding: Connecting planks and frames.
- Concrete Formwork: Holding wooden forms together during concrete pouring.
- Temporary Bracing: Providing support during construction projects.
- Stage Construction: Building temporary sets and platforms.
