Sheradised Square Twist Nails 30mm (1000/Box)

3.1 x 30mm Sheradised Square Twist Nails for heavy-duty timber-to-timber fixings and structural reinforcement work.Manufactured from high-strength carbon steel with a durable sheradised zinc coating, these nails offer improved corrosion resistance and long service life in both interior and exterior applications. The square-twisted shank increases surface area and creates a threaded effect within the timber, providing exceptional grip and preventing loosening over time. The countersunk head ensures a flush finish with the surface for improved appearance and easier overpainting, while the diamond-bevelled tip enhances driving accuracy and reduces the risk of timber splitting. 30mm size suitable for joist hanger installation, flooring, and heavier framing applications.
