Abstract
Apparatus and method for forming a pin and nut fastener assembly for temporarily or permanently securing two panels having conventional drilled generally aligned holes into which the assembly is inserted. Weight of the pin and nut is reduced while retaining predetermined industry established strength requirements. The thread section of the pin is reduced along with the mating thread of the nut. The pin may be cold-worked in critical areas.
