It is a mechanical fastener that provides a thread feature in applications with a single side access. It is available in aluminium, steel and stainless steel, with different protective coatings that avoid the effects of external agents. It is a universal insert nut suitable for applications involving very resistant materials where a hexagonal drill is not possible. It is particularly used in levelling work. Features Universal insert nut appropriate for very resistant materials where a hexagonal drill is not possible. It is ideal for levelling work. Excellent solution to obtain a resistant and reliable thread in parts with a reduced thickness (0.5 mm.). Single-sided access (blind insert nut). Valid for use in a great variety of materials where the alternative methods (nuts, welded nuts, etc.) do not maintain the clamping force and the tensile load. Versatility. Double function: as a nut and as a joint rivet. It is available in three different types of heads: large, reduced and
