US Patent 9976591 Bolt and cap assembly for plumbing fixture

A bolt and cap assembly for mounting a plumbing fixture includes a flanged nut, a bolt, a washer, and a cap. The flanged nut includes a flange and a sleeve extending therefrom. The bolt includes a substantially planar head and a shaft extending therefrom. The shaft is configured to threadably engage the flanged nut to couple the plumbing fixture to a mounting flange. The washer is configured to be positioned between the bolt and the flanged nut. The cap is configured to be removably coupled to the washer and to encase the substantially planar head of the bolt between the washer and the cap so as to conceal the substantially planar head from view and to prevent fluid from entering an area between the cap and the washer.
