Nyloc Self Clinching Nut

About Nyloc Self Clinching Nuts

Nyloc Self Clinching Nuts provide a strong reusable female thread in panels that are too thin to be conventionally tapped. A nylon element provides a reusable non-metalic prevailing torque locking feature suitable for use in temperatures up to 120°C.

Utilising a special proven clinch formation, along with a radially knurled collar, this fastener has excellent torque out and push out characteristics whilst installing flush on the underside of the panel.

Available in Steel and Stainless Steel in thread sizes M3 - M5.

Like all self clinching fasteners they are installed using a parallel squeezing action so require access to both sides of the panel.

Note: This part may be used in panels from 1.0mm to 1.49mm if the fastener is not installed with the knurling collar fully flush. The knurled collar must be left proud of the panel as if the sheet thickness was 1.5mm or less. Incorrect installation of this fastener may result in the collar fracturing in panels thicker than 1.7mm where the mating screw is tightened past the maximum recommended torque.
