Info
Self-Clinching 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 the underside of the panel.   Like all self clinching fasteners they are installed using a parallel squeezing force so require access to both sides of the panel.   Clinch Nuts are available in various thread sizes, manufactured from electro zinc plated steel, 300 and 400 series stainless steel, and aluminium and are suitable for installation in ductile steel and aluminium panels with a recommended maximum hardness of 80 HRB for steel parts, 70 HRB for 300 series stainless steel parts, 90 HRB for 400 series stainless steel parts and 50 HRB for aluminium parts.
