    Abstract: The present disclosure provides flanged joint or interface between two passageways. The flanged joint includes a first passageway, a connector, and a second passageway. The first passageway may, but not necessarily, be formed via casting process wherein an integrated flange may be defined at the opening of the first passageway such that the integrated flange defines a recess. The connector includes a support body having a fastener region at an upper end of the support body and a flange region at a lower end of the support body. The support body defines an aperture which is configured to support the second passageway. The flange region defined in connector is configured to engage with a recess defined in the first passageway.

    Abstract: A joint assembly includes a first container portion, a second container portion, a band strip, and a fastener. The first container portion has a first flange including a first sealing surface and a first outer surface. The second container portion has a second flange including a second sealing surface and a second outer surface. The second sealing surface is configured to cooperate with the first sealing surface to form together a sealed connection. The fastener is configured to attach the band strip to one of the first and second container portions. An inner surface of the band strip is configured to engage at least one of the first and second outer surfaces such that the sealing surfaces of the first and second flanges are fixed with respect to one another when the band strip is attached to at least one of the first and second container portions.

    Abstract: A limiting spring washer includes a main body portion and a side portion, which may be a frustoconical, extending from the main body portion. The main body portion defines a washer aperture therethrough. The main body portion is thicker than the side portion. A bolt assembly includes a part defining a part aperture therethrough. A limiter is disposed within the part aperture. A bolt is configured to attach the part to an item. In the bolt assembly, the limiting spring washer is disposed in contact with the limiter, the bolt, and the part. The bolt is configured to apply a total load, a first portion of the total load being absorbed by the part, and a second portion of the total load being absorbed by the limiter.

    Abstract: A self-tapping compression limiter for a structure of an automotive vehicle. The limiter includes a body having a first end extending to a second end. The body has a bore formed through the first and second ends defining a longitudinal axis. The body has an outer wall having a shoulder radially extending from the outer wall and formed adjacent one of the first and second ends to reduce tolerance to the structure. The outer wall has a threaded portion formed about the longitudinal axis. The threaded portion is matingly cooperable with the structure to provide a positive lock interface between the limiter and the structure.
