Apparatus and method for forming a pin (13) and nut (24) fastener assembly for temporarily or permanently securing two panels (11, 12) having conventional drilled generally aligned holes into which the pin is inserted. Weight of the pin and nut is reduced while retaining predetermined industry established strength requirements. The thread section (15) of the pin is reduced along with the mating thread (27) of the nut. 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. L'invention porte sur un appareil et sur un procédé de formation d'un ensemble de fixation d'axe et d'écrou destiné à fixer provisoirement ou définitivement deux panneaux dont les trous alignés et percés de manière traditionnelle accueillent l'ensemble de fixation. Le poids de l'axe et de l'écrou est réduit, cet ensemble présentant également des caractéristiques répondant aux normes industrielles prédéfinies de résistance. La partie filetée de l'axe est réduite, de même que le filetage correspondant de l'écrou. L'axe peut être écroui dans des zones critiques.
