ABSTRACT:
The invention features an improved flush installation multi-part interlocking nail fastening system which eliminates loosening of flooring members, rubbing, or relative movement, thereby eliminating squeaks and noises. A master nail with modified head and shank portions accepts insertion of two smaller nails of soft composition which, when driven into a pair of internal longitudinal bores, these small nails exit the master nail to form opposing arcs, pulling abutting floor members into tight abutting engagement.
