A hybrid fastener assembly includes a body and a removable insert. The removable insert includes a first flange having a first circular hole. The body includes a receptacle, a second circular hole, a retention mechanism, and a plurality of lateral walls. The removable insert is accommodated in the receptacle and is inserted in a lateral direction perpendicular to a central longitudinal axis of the body. The second circular hole aligns with the first circular hole to form a channel for receiving the threaded fastener. The retention mechanism secures the removable insert inside the receptacle. At least two lateral walls include a snap lock for mounting the hybrid fastener assembly to a first component.

Separation device assemblies include a first plate defining respective contact surfaces and engagement surfaces and a second plate defining a respective contact surfaces and engagement surfaces. A fracture groove is located on separation walls of the first and second plates. A first end member, a second end member, and the separation wall of the first plate define a first plate expansion device channel and the second plate defines a similar second plate expansion device channel. When assembled, the first plate and the second plate form an expansion device cavity and the first and second plates form a frangible joint. The respective engagement surfaces are configured to engage with receiving channels of attachable mounting devices.

A hook includes a hook seat, a rivet, and a fixing bolt. A rivet cap and a rivet post are provided on the rivet. The rivet post includes a rivet rod and a rivet seat. A diameter of the rivet seat is greater than a diameter of the rivet rod. A first step is formed between the rivet rod and the rivet seat. A first cut surface and a second cut surface are provided on both sides of the rivet rod, respectively. The rivet and fixing bolt are matched with each other and fixed to the hook seat. The first step abuts against one side of the hook seat. An end face of the fixing bolt abuts against the other side of the hook seat to lock the hook seat between the fixing bolt and the first step.

A connection assembly for robot joints, including: a first joint provided with a first connection end, where a connection base is provided on the first connection end, and the connection base is provided with a first connection protrusion extending radially outward; a second joint provided with a second connection end, where a connector is provided on the second connection end, and an external thread is provided on an outer circumference of the connector; and a connection nut adapted to be rotatably sleeved on the connector, where an internal thread is provided on an inner circumference of the connection nut, a second connection protrusion extending radially inward is formed at an end of the connection nut facing the first connection end, and the second connection protrusion is sleeved on a radial outer side of the connection base, such that the first connection protrusion is accommodated in a space, facing the second joint, formed by the second connection protrusion. The problem of complicated assembly and disassembly of joints of a collaborative robot is solved.

An electrical connector including a mounting flange defining a mounting hole extending therethrough that is configured to receive a threaded fastener and a deformable crush rib extending from the mount flange and surrounding the mounting hole is presented herein. A method of assembling an electrical connector to a panel including the steps of inserting a fastener within a mounting hole of a mounting flange defining the mounting hole extending therethrough and a crush rib surrounding the mounting hole, applying a clamping force to the mounting flange via the fastener, and deforming the crush rib via the clamping force applied by the fastener such that the deformed crush rib at least partially fills a gap between an inner wall of the mounting hole and the fastener is also presented herein.

An adapter clip includes a first portion configured to fit within an engine clip or an engine clamp, a second portion including an annular portion, the annular portion being configured to fit around an engine component, and a web portion connected to the annular portion and the first portion. A diameter of the first portion differs from a diameter of the annular portion.

Systems and methods for sealing bolted flange joints to stop or prevent leakage are disclosed. The system includes a sealant injection nut. The sealant injection nut generally comprises a threaded nut configured to be threaded onto a stud bolt of a flange joint. The nut is configured to inject sealant into the internal passages of the flange joint. The nut includes a passageway drilled through the sidewall. Fitted to the passageway is a high-pressure sealant-compatible injection fitting and an internal check-valve. Provided within the central cavity of the nut, at the flange-facing end, is a groove that facilitates the flow of sealant injected through the passageway into the passages of the bolted flange. A method is also provided for manufacturing the sealant injection nut. A method is also provided for repairing leaking bolted flange joints using the sealant injection nut.

A mounting feature for an attachable component includes a mounting tab and an integrated retaining feature. The mounting tab includes a tab body having a first end surface and a second end surface formed on an opposite side from the first end surface. A distance from the first end surface to the second end surface defines a thickness of the mounting tab. The mounting tab further includes an inner wall defining a socket having a first width that extends through the thickness of the tab body from a first end at the first end surface of the tab body to a second end at the second end surface of the mounting tab. The retaining feature is disposed within the second of the socket and includes a receptacle having a second width that is less than the first width of the socket. The receptacle is configured to capture fastener shank.
