1. Increased durability of the structure
Thanks to the use of carbon steel, our nails ensure exceptional strength and stability of connections, which translates into longevity and reliability of the entire structure.
2. Widening under the head
The conical widening of the shank diameter under the nail head significantly reduces initial displacement when load appears. This ensures greater stability of connections from the very first stages of assembly.
3. Excellent pull-out protection
The specially profiled rings of our nails significantly increase their pull-out resistance, which is crucial in places where connections are exposed to intense dynamic loads.
4. Corrosion protection
Electrolytic galvanizing with a layer thickness of at least 12 μm protects the nails from harmful atmospheric influences, which is particularly important in outdoor conditions.
5. Usage class 2
Characterized by material moisture corresponding to a temperature of 20°C and relative humidity of the surrounding air exceeding 85% only for a few weeks a year.
6. Service class 3
Corresponds to conditions causing wood moisture content higher than that corresponding to service class 2.
Application and installation method
The use of CNA nails (or CSA screws) is a necessary condition for achieving the full load-bearing capacity of the connection using Simpson Strong-Tie carpentry joints.
