A floating
fastener mounting structure includes a mounting socket having a locating groove extending around the periphery and defined between a relatively smaller annular step and a relatively larger stop
flange thereof, a
metal panel member having a mounting through hole attached to the mounting socket and stopped above the stop
flange and stamped by a
stamping press to provide a riveting portion and to force the riveting portion to engage into the locating groove and to wrap about the stop
flange of the mounting socket, a spring-loaded locking member axially slidably mounted in the mounting socket for detachably locking the
metal panel member to an external
metal panel member, and a cap member capped on a mounting head of the locking member and affixed to the mounting head during the operation of the
stamping press to stamp the metal panel member. Affixing the mounting socket to the metal panel member by riveting greatly enhances the shearing strength of the floating
fastener mounting structure.
