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 countersunk. It does not deform surfaces after the riveting process (lacquered, glazed, etc.). Available in different finishes that improve its resistance to corrosion. Its installation can be incorporated at any stage of production. Fast and high precision assembly. It can be used with ergonomic and simple tools that can be pneumatic, automatic or hand tools. The riveting process is environmentally friendly, free of smoke, sparks, fumes, etc. Specification Materials: Aluminium/Steel Diameters: M6 Heads: Large Box Quantity: 250 KINDLY REMINDER: Delivery to the UK Highlands, Channel Islands, Northern Ireland, Isle Of Wight, Isle Of Man and the following postal code areas: BT, FK, KA (1-30), PA(1-49), PA(60-78),PA80, PH, PH(11-40), PH(41-44), PH(49-50), AB, IV, KW, ZE, GY(1-10), JE(1-5), PO(30-41), IM, IR, HS are excluded from our standard delivery charge and may incur extra costs.
