Double Head Nail Making Machine – Fast & Accurate Production of Duplex Nails from 5d to 20d
The ZT double head nail making machine is a specialized nail production machine designed to manufacture double head nails, also known as duplex nails. Unlike common Z94 nail machines, this model adopts a dual-head forming mechanism that precisely forms both the upper and lower nail heads in one operation.
Double-head nails are widely used in temporary construction applications such as concrete formwork, scaffolding, and removable wood structures, where easy removal and reusability are essential.
Why Use Double Head Nails?
Duplex nails are specifically engineered for temporary structures and easy removal. Their unique two-head design prevents over-driving the nail into the material and allows for simple removal using common tools.
Key Advantages:
- ✅ Dual-head design allows for easy removal without damaging the surface
- ✅ Reusable and eco-friendly — reduces material waste and cost
- ✅ Strong holding power; optional ring shank enhances grip in wood
- ✅ Compliant with ASTM F1667 / A153 standards
- ✅ Ideal for construction, framing, event setups, formwork, and more
