US Patent 10024353 Retaining spring nutplate

A fastening assembly includes a body and a retaining device. The retaining device is secured to the body for placement along a surface. The body is configured to flex between a relaxed state and a compressed state. The body is compressed between two external surfaces in a compressed state to maintain the alignment and position of the retaining device without the fastener. The flexure of the body causes the body to exert an outward spring force against the external surfaces sufficient to maintain the location of the retaining devices before insertion of a fastener. The fastening assembly includes the fastener for insertion into the retaining device.
