Cna 4.0X50Mm Carpentry Joint Nails

Ring nails for carpentry joints 4x50 mm (250 pcs.) The most important parameters Model: CNA Size: 4x50 mm Quantity: 250 pcs. Material: galvanized steel Designed for attaching carpentry joints to wood. Original product from a renowned company SIMPSON Strong-Tie ® Product specifications total length: 50 mm thread length: 41 mm thread diameter: 4.0 mm diameter Head: 7.0 mm Quantity per package: 250 pcs Benefits 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 Conical widening of the shank diameter under the nail head significantly reduces initial displacement when load appears. This ensures greater connection stability 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 against harmful atmospheric influences, which is particularly important in outdoor conditions. 5. Service class 2 Characterized by a material moisture content corresponding to a temperature of 20°C and a 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 method of installation The use of CNA nails (or CSA screws) is a necessary condition to achieve the full load-bearing capacity of the connection using Simpson Strong-Tie carpentry joints.
