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.
