Duplex Head Nails for Construction & Formwork Projects | Factory Direct Supply

These duplex nails (double-headed nails) are designed for temporary fastening and easy removal.
Core use case: Primarily used in construction to secure wooden concrete formwork, scaffolding, and temporary bracing.
Key advantage: The second exposed head allows for quick, clean removal with a claw hammer or nail puller after use, without damaging the wood. This makes the formwork reusable and saves labor.
Other uses: Ideal for temporary assembly and positioning in carpentry, where parts need to be adjusted before permanent fastening.
