Info
Self-Clinching Flush Nuts provide strong reusable female threads in panels that are too thin to be conventionally tapped.   Utilising a special proven clinch feature, this fastener has excellent torque-out and push-out characteristics whilst providing a flush finish on both sides of the panel.   Like all self clinching fasteners they are installed using a parallel squeezing action, so require access to both sides of the panel.   Flush Nuts are available in various thread sizes, manufactured from 300 series stainless steel and are suitable for installation in ductile steel and aluminium panels with a recommended maximum hardness of 70 HRB.
