ABSTRACT:
A fastener assembly for use with a high temperature heat transfer roll and is provided for joining a sheet of insulating material to the end of said roll by utilizing a protruding bolt head or the like. The fastener assembly comprises a cup-like body defining a cavity for receiving said bolt head and a quantity of adhesive material therewithin. A plurality of inwardly extending projections in said cup-like body cavity may be used to engage the bolt head substantially in an interference fit during setting of the adhesive material. A plurality of through apertures in the cup-like body permit release of any excess quantity of adhesive material therefrom. A shaft portion is formed integral with and projects axially outwardly from the cup-like body and away from the bolt head and is of sufficient axial extent to project through the sheet of insulating material. An enlarged head is carried on an axially outermost end of the shaft portion. A clamping member includes a first surface defining a complementary fastener aperture for engaging the enlarged head and a second, abutment surface extending radially outwardly of the first surface for overlying and abutting a portion of the sheet of material to thereby secure the sheet of material in juxtaposition to the protruding bolt head.
