Product Overview
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.
