Sandwich panels, especially load-bearing panels such as aircraft floors, are fixed to support members by means of ferrules having an aperture sufficient to allow the passage of the shank, but not the head, of a bolt, by a method in which THE FERRULE IS INSERTED INTO A HOLE EXTENDING THE THICKNESS OF THE PANEL SO THAT THE BODY OF THE FERRULE LIES WITHIN THE SANDWICH PANEL AND THE FLANGE CONTACTS A SKIN OF THE PANEL, THE FLANGE IS BONDED TO THE SKIN WHICH IT CONTACTS, USUALLY BY MEANS OF A THERMOSETTING OR THERMOPLASTIC ADHESIVE, THE PANEL IS PLACED AGAINST THE SUPPORT MEMBER IN THE DESIRED LOCATION WITH THE FACE OF THE PANEL CARRYING THE FLANGE OF THE FERRULE IN CONTACT WITH THE SUPPORT MEMBER, AND THE BOLT IS PASSED THROUGH THE FERRULE AND SCREWED TO THE SUPPORT MEMBER.
