Galvanized screw nails

Due to the helical twist these nails are much more firmly attached to the tree with a force on the pull-out. This increased strength is needed to create important structures made of wood, such as the assembly of pallets, assembly floors, and roofing. Galvanizing nails allows their use in high humidity conditions, as they are much less prone to rust than black.

Black screw nail

Screw nail intended for stronger fixing of wooden elements and structures, such as laying floors, making all kinds of wooden packing containers and assembly of rigid structures. Due to the helical shape, these nails are held more tightly to the wood. Since nails are not coated with zinc, it is recommended to use them for rough work or in conditions of low humidity.
