Also known as rod anchors, they're often used with threaded rod to hang pipe and wiring. Install like a stud anchor just thread the anchor, a nut, and a washer onto the end of a threaded rod, drive into a hole, and turn the nut to expand the base. Size not listed? Please make an enquiry – we may be able to provide it. Easy-Install Female-Threaded Anchors for Concrete. = Zinc Plated Steel // = A2 Stainless Steel // = A4 Stainless Steel Non-standard sizes and materials are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Rivet Nut Countersunk Knurled Closed End are available in diameters from M3 to M12 to suit various grip ranges.Īvailable at Fastenright in Zinc Plated Steel, A2 Stainless Steel and A4 Stainless Steel as standard. Installing these rivet nuts is simple, using a special tool with a threaded stud, or nose, that engages with the internal threads of the rivet nut and pulls upwards, deforming the unthreaded section of the rivet nut to expand under the reverse side of the material – providing a high strength permanent thread in a thin sheet material. The closed-end blocks any form of contamination getting to the component, and also prevents the use of screws that are too long for the application. The presence of the knurled body on the rivet nut provides greater resistance to movement within the application than knurling under the head, especially when installed in softer materials. Both types offer a flush, finished appearance to the application. Where the thickness of the application is smaller, the reduced countersunk type is often chosen instead. The full countersunk head is chosen over a reduced countersunk head type due to its stronger nature, however it is also deeper, meaning that it can only be used in material thicknesses greater than 1.5mm. ![]() ![]() Rivet Nut Countersunk Knurled Closed End, also referred to as Rivnuts, Blind Nuts and Nutserts®, are an internally threaded insert often used when the thickness of the application at hand is too small to tap a standard thread.īy using rivet nuts, a strong thread is created in thin sheets of material, for high strength fastening from bolts and other threaded articles.
