Sheradised Square Twist Nails 25mm (1000/Box)

3.1 x 25mm Sheradised Square Twist Nails designed for medium-duty timber fixings, reinforcement work, and secure attachment of joist hangers and restraint straps.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. 25mm size suitable for medium-duty structural fixings and reinforcement work.
