Fastener system for leak resistant structural member attachment

Abstract

Embodiments herein relate to structural assemblies for fenestration units including a fastener system for leak resistant structural member attachment. In an embodiment, a frame assembly for a fenestration unit is included having a first frame member and a second frame member, wherein the second frame member engages with the first frame member. The frame assembly further includes a leak resistant fastener assembly securing the second frame member to the first frame member. The leak resistant fastener assembly can include a threaded fastener, a shoulder element, a deformable sealing member, and a washer. Insertion of the threaded fastener into the first frame member and the second frame member causes the washer to compress the deformable sealing member forming a face seal and causes the shoulder of the threaded fastener to expand the deformable sealing member radially forming an edge seal. Other embodiments are also included herein.
