Info
Self-Clinching Miniature Nuts provide strong reusable female threads in panels that are too thin to be conventionally tapped where space is at a premium or installation very close to the edge is required.   Utilising a special proven clinch feature in combination with a radially knurled collar, this fastener has excellent torque-out and push-out characteristics whilst providing a flush finish on the underside of the panel. Available in non-locking and locking versions, the locking version features an elliptically deformed body plus a dry film lubricant to provide prevailing torque locking capability to limit loosening under vibration.   Like all self clinching fasteners they are installed using a parallel squeezing action, so require access to both sides of the panel.   Miniature Clinch Nuts are available in various thread sizes, are 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.
