Abstract
An insertable moldable ratchet rivet assembly of a unitary construction for securing a plurality of panels together includes a drive-pin insert of a unique construction to facilitate the pull-up operation with a reduced amount of force and to form slots in the shank of a rivet housing. The drive-pin insert includes a body portion having a plurality of segments which are spaced apart from each other to form recessed flattened surfaces therebetween. Each of the flattened surfaces is provided with a plurality of lengthwise-spaced horizontal teeth. The rivet housing includes a head flange and a shank. The rivet shank is formed of a plurality of shank wall portions extending substantially from the rear surface of the rivet head flange. The plurality of shank wall portions are spaced apart from each other to provide slots therebetween which are formed by the plurality of segments on the body portion of the drive-pin insert.
