Die Buttons and Retainers
Die Buttons
The Die Button, held firmly in the die by the Retainer, forms the
part material into and around the Pierce Nut and undercuts and/or
clinches the nut corners to secure it in position. Additional
die buttons, other than those shown below, are available for special
applications. Consult your representative.
