Select the appropriate hole size from the table below for the fastener size required. Punch the hole diameter into the sheet material. Place fastener into anvil recess. Place the sheet over the fastener spigot so that it rests on the fastener serrations.  Ensure both plate and fastener are aligned along the same axis.

Apply squeezing force, ensuring that the punch and anvil surfaces are parallel, until the retainer shoulder makes contact with the face of the sheet.

The serrations if properly installed will provide torsional (rotational) resistance. After installation the spigot joint should be flush with the sheet metal.
