M3 x 9mm Rivet Nut Countersunk Knurled Type in A2 Stainless

The countersunk head on these rivet nuts offer a flush, non-interfering fit when installed into a suitable countersunk hole. As with the flat head, the countersunk head can be used to clamp a single or multiple sheets of materials. The knurling on the body helps the rivet nut grip the connecting surface and help to prevent it turning. The open ends allows the rivet nut to be used with longer lengths of bolts. Used in a multitude of industries such as aerospace, automotive, rail, HVAC, white goods, electronics, DIY and general engineering.
