A punch is positioned opposite to the clinching punch and is configured to form an aperture in the first layer prior to the clinching punch engaging the second layer. A retractable clinching die configured to contact the first layer and to shift such that an interior wall thereof is angularly offset from an initial position when contacted by a portion of the second layer extending through the aperture of the first layer.
