ABSTRACT OF THE DISCLOSURE
Fastener for securing a resilient thermal insulation
blanket onto a base to form a surface to be walked on. The
fastener has a washer-like thin disk applied over the blanket
and having a central hole. A tubular depression member depends
from one surface of the disk, this member having the form of an
elongated wall of which the length is approximately half the
thickness of the blanket. The wall has a bore in communication
with the disk central hole and a bottom wall having a through
passage of a diameter smaller than that of the base. A screw
having a threaded stem and head is mounted in the well with the
stem thereof extending through the passage through the well
bottom wall. This screw is secured onto the base until the head
stands generally at the bottom of the well.
