Rivet Nut Countersunk Head Plain Body Closed End fasteners are a form of internally threaded insert, used in applications where a wall’s thickness is too small to tap a conventional thread.
The countersunk head allows it to be used within applications without extra hole preparation and allows it to sit flush into the application’s housing hole. They can be installed into pre-coated applications without damaging the surface.
Countersunk Head Plain Body Closed End Rivet Nuts are typically used to stop moisture or other contaminants from getting close to or into the product.
Manufactured in A2 Stainless Steel, and A4 Stainless Steel – which contains a higher percentage of Nickel and Molybdenum – making it perfect for marine, coastal or even industrial applications.
Available at Fastenright in sizes M4 to M10 as standard.
Non-standard sizes and materials are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Minimum order quantities apply.
