Product Overview
3.1 x 20mm Sheradised Square Twist Nails for secure fixing of joist hangers, restraint straps, and light timber-to-timber connections.
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.
20mm size suitable for light-duty structural fixings and reinforcement work.
