Abstract

A push nut and a male member are disclosed having cooperating buttress threads. The push nut is divided into sectors, each of which has multiple segments that comprise the nut's thread. The adjacent edges of the successive sectors are connected to each other by a resilient corrugation arranged to distribute the stress equally between the ends of each thread segment and equally among the thread segments of each sector.
