Abstract
A die button for installation of a nut to a panel includes a button body with a panel end, and a cavity defined therein. An aperture is defined in the panel end at a mouth of the cavity. A shearing edge is at a perimeter of the aperture to shear a tab from the panel when a shearing force is applied to the panel by the nut driven by a punch of a press. A relief is in a portion of the perimeter of the aperture to bend a root portion of the panel connecting the tab to the panel without severing the root when the nut applies the shearing force. A reaction member is slidably disposed within the cavity. A resilient member is disposed within the cavity to urge the reaction member toward the panel end, thereby bending the tab to contact the nut and seal a bore.
