Rivet Nut Flanged Knurled Closed End

Rivet Nut Flanged Knurled Closed End are internally threaded inserts used in applications where the material thickness is too small to tap a conventional thread. By using rivet nuts, a strong thread is created in thin sheets of material for high strength fastening from bolts and other threaded articles.

The large diameter of the flanged head is used to reinforce the hole and increase resistance to pull-out, making this style of head ideal for load-bearing applications. The closed-end is used in applications to reduce corrosion from moisture or contamination, whilst also preventing screws that are too long from being used in the application.

The knurled body of the countersunk rivet nut helps to prevent rotation within the application, especially when installed in softer materials, providing extra resistance to vibration – more than the smooth-bodied version.

Flange head rivet nuts with a knurled body and closed end are installed using a special tool, with a threaded stud that engages with the internal threads of the rivet nut and pulls upwards. This deforms the unthreaded section of the rivet nut to expand under the reverse side of the material, providing a high strength permanent thread.

Available in diameters from M4 to M10 to suit various grip ranges. Materials and finishes available include Zinc Plated Steel, A2 Stainless Steel, A4 Stainless Steel and Aluminium. Other materials and sizes can be made to order.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.
