Info
Self-Clinching Nyloc Nuts provide strong female threads in panels that are too thin to be conventionally tapped. A nylon element provides a reusable non-metallic prevailing torque locking feature suitable for use in service temperatures up to 120°C.   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. Like all self clinching fasteners they are installed using a parallel squeezing action, so require access to both sides of the panel.   Nyloc Clinch Nuts are available in various thread sizes, are manufactured from electro zinc plated carbon steel and 300 series stainless steel and are suitable for installation in ductile steel and aluminium panels with a recommended maximum hardness of 70 HRB.
