The Cemintel Rivet Centralising Tool is designed to take the guesswork out of drilling into top hat sections, ensuring every rivet is seated correctly for a professional finish. The primary function of the Surround Rivet Centralising Tool is to provide a guide for drilling 4.1mm rivet holes. By using the pre-drilled holes in the Cemintel panels as a guide, the tool ensures the hole in the underlying top hat is perfectly centred. This prevents misaligned rivets that can lead to panel stress or aesthetic inconsistencies.
