A bolted joint for coupling two components that undergo thermal expansion and contraction includes a bolt having a head and a stem, the bolt configured to provide a clamping force between the two components. A first washer having a thermal resistant, low friction coating is configured to be disposed between one of the two components and the bolt head to enable the one component to slide relative to the bolt during the thermal expansion and contraction, while maintaining the clamping force, to facilitate preventing bending or shearing of the bolt.

A nut cap assembly for securing an internal component to an external component includes a seal cap having a base and a shroud extending from the base. The base includes a mounting flange configured to be mounted to the internal component. The base includes an opening at a mounting end of the base configured to be mounted to the internal component. The base includes a seal groove surrounding the opening configured to receive a seal. The seal groove is open at the mounting end to interface the seal with the internal component. The shroud includes a nut pocket has a cap anti-rotation feature. The nut cap assembly includes a nut received in the nut pocket. The nut includes a threaded bore configured to threadably receive a threaded fastener used to secure the internal component to the external component. The nut includes a nut anti-rotation feature interfacing with the cap anti-rotation feature.

A fastening system for suspended installation of stowage compartments, in particular in aircraft, includes a first fastening element, which fastens on a supporting structure, a second fastening element, which fastens on a stowage compartment, and a connecting arrangement, configured for surface-area fastening on the first fastening element. The connecting arrangement and the second fastening element each include a supporting eyelet for accommodating a fastening bolt, to fasten the connecting arrangement on the second fastening element. The first fastening element and the connecting arrangement each include a fastening surface for fastening on one another, and therefore a continuous insulation layer can be positioned between the fastening surfaces, or between the supporting structure and the first fastening element, for the purpose of insulating the supporting structure, in order for the supporting structure alone or together with the first fastening element to be insulated throughout in relation to the connecting arrangement.
