Full Nuts Self Colour [Fine Thread]

• These hexagon nuts are self colour without any corrosion resistance.
• The hexagonal shape is designed to be driven by a wrench (spanner) and provides excellent torque when done so.
• Fine thread.

Self coloured finishes have no protection against corrosion, and are more suited for use in internal joinery applications. Self colour finishes have no definitive colour and can vary with the effects of natural oxidisation and weathering, from a bright zinc finish to a dark black colour. Before being used in exterior environments, they should be coated or painted with a protective covering.

Fine Threads

Fine thread bolts (size for size) are stronger than a coarse thread, both in tension and shear. They also have less tendancy to loosen and allow for finer adjustments in applications that need such a feature. Fine threads can be more easily tapped into hard materials, and require less torque for equivalent preloads. However, they are more susceptible to galling, require longer thread engagements, and are more prone to damage. They are not suitable for high speed assembly since they are more likely to sieze when being tightened.
