A shear pin assembly for securing to a face sheet of a honeycomb core sandwich panel structure and to engage a support structure, which includes a head member having a first width dimension and a neck section secured to the head member with the neck section having a second width dimension less than the first width dimension. Further included is a flange secured to the neck section with the flange extending in a direction away from the neck section and a pin member which extends from the flange in a direction away from the head member.

A wire harness fixing structure includes a plate-like member including a first layer and a second layer softer than the first layer, an electrical wire disposed along the plate-like member, and a fixing member attached to the electrical wire to fix the electrical wire to the plate-like member. The fixing member includes: a through locking piece formed to be able to pass through the first layer and locked to the first layer while passing through the first layer, a regulation piece provided with a space between the regulation piece and the through locking piece to stop the through locking piece from passing through a surface of the plate-like member, and a column connecting the through locking piece and the regulation piece.

A method of making an assembly is disclosed. According to the method, a curable sealant is applied to a metal surface of a first article, and the curable sealant and first article are stored under conditions to maintain the curable sealant in an at least partially uncured state. The method further includes contacting the curable sealant on the first article metal surface with an electrically conductive surface of a second article, and curing the curable sealant.

A connection mechanism (4) comprises first and second components (6, 8) which can be selectively coupled together, one of the first or second components comprises a locking member (25) which is moveable between a first state and a second state, the other of the first or second component comprises means (16) for initially moving the locking member from the first to the second state as the first and second components are initially drawn together and means (19) for returning the locking member to the first state once the first and second components are fully engaged together to prevent disengagement of the first and second components.

Disclosed herein is a rotational roller apparatus for use with a pipeline unit. The pipeline unit is received in a pipeline for welding and/or inspection. The rotational roller is attached to and is able to support at least a portion of the weight of the pipeline unit. The rotational roller unit also includes an extension member and a reduced friction base. The reduced friction base is attached to an end of the extension member so that the rotational roller has a retracted and an extended configuration. In the extended configuration, the reduced friction base contacts an interior of the pipeline and supports at least a portion of the weight of the pipeline unit and thereby allows the unit to be rotated about a longitudinal axis within the pipeline.

A method for producing and installing a fastener, including the steps of forming an engaging portion having a projecting stem which is interiorly hollowed over at least an intermediate extending range, the stem including a solid end most extending portion, and forming a receiving portion having a surface, within which is configured an inner rim defined edge, a diameter of an aperture between said rim edge being less than a diameter of the stem. Additional steps include pressing the solid end most extending portion of the engaging portion through the inner rim edge of the receiving portion and aligning with the inner rim edge a location of the interiorly hollowed portion of the stem, causing inward collapsing of the aligned location by the rim edge to secure the engaging portion to the receiving portion.

A stud pin includes a first shaft part that extends in a first direction, a first flange portion that is provided coaxially with the first shaft part at one end portion of the first shaft part, a second flange portion that is larger than the first flange portion provided coaxially with the first flange portion on a side opposite to a surface of the first flange portion, on which the first shaft part is provided, and a second shaft part that is provided coaxially with the second flange portion on a side opposite to a surface of the second flange portion, on which the first flange portion is provided, and extends in a second direction opposite to the first direction.

A connection assembly adapted to join a surface element to an underlying support structure while maintaining a substantially zero gap abutting relation between the surface element and the support structure. The connection assembly includes a press-in retainer with a circumferential seal having a sealing foot. The sealing foot flexes about a living hinge while maintaining continuous sliding contact with the support panel without interfering with downward movement of the retainer.
