Clout Nails - TIMco - Silver - 40 x 3.00mm

These nails are ideal for applications requiring significant clamping force, such as fixing roofing felt and plasterboard to timber structures.

Yes, they are suitable for outdoor use in Service Class 2 environments, meaning areas that are occasionally damp or wet, rural, and sheltered. They are not recommended for constant exposure to moisture or coastal conditions.

Service Class 2 refers to conditions where the moisture content of the timber is influenced by the external environment but is protected from direct weather. This includes buildings with unheated spaces or structures in sheltered rural areas.

A 1kg pack contains approximately 350 nails.

The head type is an extra-large round head, with a diameter of 76.42mm and a length of 40mm.

The nails are made from carbon steel.

While strong, they are designed for general fixing and clamping. For specific structural applications, always consult engineering specifications and use fasteners designed for those purposes.

Ensure the hammer strike is direct and firm. Check that the substrate is not excessively hard or that the nail length is appropriate for the material thickness. Use a heavier hammer if necessary, but maintain control.

Verify that the extra-large head is appropriate for the material being fixed. Ensure the nail is driven fully so the head is flush with or slightly embedded in the surface material.

The nails are rated for Service Class 2; if used in a more aggressive environment (e.g., constant moisture, salt air), accelerated rusting may occur. Relocate the project to a more suitable environment or consider a higher-rated corrosion-resistant fastener.
