ABSTRACT:
An improved adhesive mounted nutplate assembly and related installation method are provided for secured mounting of a nutplate or the like onto a substrate, particularly at a blind side of the substrate in alignment with an access opening. The nutplate assembly includes a nut member having a resilient fixture pin received therein, with the nut member being adapted for adhesive mounting onto the blind side of the substrate with the fixture pin extending through the access opening. A pulling force applied to the fixture pin draws the nut member with a positive force against the substrate. The fixture pin is sized to bind within the access opening when released to maintain this positive force for the duration of an adhesive cure period, after which the fixture pin can be forcibly drawn through and removed from the nut member. A preferred nut member comprises a nutplate having a floating nut carried by a base which is adapted for adhesive mounting onto the substrate. An improved adhesive applicator is also disclosed.
