Abstract: A method for installing and securing mechanical elements, such as standoffs and pins, in a plate includes the steps of forming suitable apertures for the elements as desired locations in the plate. First ends of each standoff and pin are inserted into their respective apertures with a portion of each standoff and pin extending through the plate. Pressure is applied to the plate, the standoff and the pin to simultaneously secure the elements to the plate. In a preferred embodiment, the end of each standoff extending through the plate is stamped or rolled over to form a retaining flange. The pins are preferably clenched to the plate by pressing an inverted V-shaped ring into the surface of the plate surrounding each pin. An apparatus for installing standoffs and pins in a plate is also provided.
