The fastener assembly includes an attachment member having a construction for affixing to a substrate as well as a first fastener member preferably in the form of a male threaded stud. The fastener assembly further includes a cap fastener. The cap fastener includes a cap member and a second fastener member preferably in the form of a female threaded extension for threadably affixing to the first fastener member. The cap member has an exterior side and an interior side. The cap member's exterior side preferably has a shape for rotation by a tool. Meanwhile, the cap member's interior side has a circular recess concentric with the cap fastener's female threaded extension. When assembled, the circular recess forms a circular insulating cavity between the cap member and an insulation blanket. ## Claims ### Claim 1 A fastener assembly for affixing an insulation blanket onto a substrate, the attachment assembly comprising: an attachment member for attachment to a substrate, said attachment member including a first fastener element in the form of a male threaded element; a cap fastener including a second fastener element made of metal and a radially enlarged cap member made of plastic and having an exterior side and an interior side, said second fastener element having a head and a female threaded extension constructed to affix to said first fastener element's male threaded element, said cap member encapsulating said second fastener's head so as to prevent rotation of said cap member relative to said second fastener element, said second fastener element's female threaded extension extends from said cap member's interior side; and said cap member's exterior side includes a hexagonal projection and said cap member's interior side a circular recess surrounding said second fastener element's extension creating a circular insulating cavity. ### Claim 2 (depends on 1) The fastener assembly of claim 1 wherein said cap member is made of polyimide and said second fastener element is made of stainless steel. ### Claim 3 (depends on 1) The fastener assembly of claim 1 wherein said attachment member includes a base for adherence to a substrate. ### Claim 4 (depends on 1) The fastener assembly of claim 1 wherein said cap member's interior surface has a substantially concave surface forming said circular recess. ### Claim 5 A fastener assembly affixing an insulation blanket onto a substrate, the attachment assembly comprising: a substrate; an insulation blanket having a mounting hole; an attachment member including a base adhered to said substrate and a male threaded element; a cap fastener including a radially enlarged cap member made of plastic having a radial size and shape greater than said mounting hole, said cap member having an exterior side and an interior side, said cap fastener further including a second fastener element made of metal which includes a head and a metal female threaded element extending from said cap member's interior side projecting at least partially through said mounting hole to threadably affix to said male threaded element, wherein said cap member's interior side overlies and engages said insulation blanket in a region surrounding said mounting hole so as to affix said insulation blanket to said substrate; and said cap member encapsulates said head so as to prevent rotation of said cap member relative to said second fastener element, said second fastener element's extension extends from said cap member's interior side, said cap member's interior side having a substantially concave surface forming a circular recess surrounding said second fastener element creating a circular insulating cavity in conjunction with said insulation blanket. ### Claim 6 (depends on 5) The fastener assembly of claim 5 wherein said second fastener element's head has a diameter larger than the diameter of said blanket hole.
