The countersunk slotted barrel nut has a smooth barrel under the head, maintaining a smooth, sleek look throughout it’s design. They are available as open head and closed head styles. Regular rivet nuts, also known as flat head rivet nuts, have a flat head that sits above the surface of the material. This makes them easier to install, as they do not require a countersink hole. Regular rivet nuts also tend to be more resistant to PUSH THROUGH than countersunk rivet nuts, as the flat head provides more grip on the top side of the material. However, the protruding head may not be desirable for applications where a smooth, flush finish is desired (i.e., aerodynamics). It ultimately depends on the specific needs of your project. Help to Choose Between Countersunk Rivet Nuts and Regular Rivet Nuts. Regular rivet nuts, also known as flat head rivet nuts, are the most commonly used type of rivet nut. These are considered the “original” rivet nut and are widely used in all applications throughout the world, especially heavy-duty construction or industrial applications. A regular rivet nut is shown below and has the following characteristics:

Dependant on size, these fasteners are available in A2 Stainless Steel, Brass and Steel Zinc as standard.

Installed with a special tool, these Countersunk open-end rivet nuts with a knurled body are engaged by the tool’s threaded stud which pulls upwards and deforms the unthreaded section of the rivet nut, causing expansion under the reverse side of the material and providing a high strength permanent thread in thin sheet material. 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. When it comes to fastening materials together, rivet nuts or Rivnuts®, are a popular choice. But when should you choose countersunk rivet nuts over regular rivet nuts? This guide will help you understand the differences between the two and make an informed decision for your specific needs. What are Rivet Nuts? Available from Fastenright in materials and finishes that include Zinc Plated Steel, A2 Stainless Steel and A4 Stainless Steel.Available at Fastenright in Zinc Plated Steel, A2 Stainless Steel and A4 Stainless Steel as standard. By using rivet nuts, a strong thread is created in thin sheets of material, for high strength fastening from bolts and other threaded articles.

Slotted countersunk sleeve nuts are ideal for applications where a flush fixing is required as the countersunk head sits flush into pre-counter-bore holes – providing a sleek and continuous flow with the surface of the application. The knurled body of the countersunk rivet provides increased resistance to turning in the application, especially when installed in softer materials. The open end style allows the stud or male threaded component to thread through the rivet nut without limiting the length or protrusion of the male threaded part.
