Abstract: A hinge assembly for mounting a toilet seat to a toilet bowl includes a hinge post and a fastener for securing the hinge post to the toilet bowl. The fastener includes a threaded portion configured to extend into a bore of the toilet bowl, a first segment coupled to an end portion of the threaded portion, a second segment configured to be engaged by a tool to rotate the fastener, and a shear segment connecting the first and second segments. The shear segment has a lower torque resistance than the first and second segments such that the shear segment breaks when a torque applied to the second segment reaches a predetermined amount. The hinge assembly also includes a nut threadably coupled to the threaded portion of the fastener. The threaded portion, the first segment, the second segment, and the shear segment of the fastener are unitary.

Abstract: A hinge assembly for mounting a toilet seat to a toilet bowl includes a hinge post, a bolt having a head and a threaded shaft configured to extend into a bore in the toilet bowl for securing the hinge post to the toilet bowl, and an adaptor having a first segment coupled to the head of the bolt, a second segment, and a shear segment connecting the first and second segments. The first and second segments are both configured to be engaged by a tool to rotate the bolt. The shear segment has a lower torque resistance than the first and second segments such that the shear segment breaks when a torque applied to the second segment reaches a predetermined amount. The head of the bolt is fit into the adaptor such that the first segment of the adaptor surrounds the head.

Abstract: A hinge assembly for mounting a toilet seat to a toilet bowl includes a hinge post, a threaded fastener extending through the hinge post and configured to extend into a bore in the toilet bowl, a bushing positioned around a portion of the threaded fastener, and a nut threadably coupled to the threaded fastener. The nut includes an expandable section configured to extend into the bore in the toilet bowl. The nut has a surface that is engaged by a surface of the bushing so that the expandable section of the nut expands as the nut moves relative to the threaded fastener to secure the hinge post to the toilet bowl.
