According to one aspect, embodiments of the invention provide a self-aligning connector system for connecting an actuator to a valve body of a valve, comprising an actuator adapter plug having a conical protrusion and a peripheral groove formed in an outer surface of the actuator adapter plug, and a valve adapter sub-assembly comprising an outer housing having a bore configured to receive the actuator adapter plug, and an expansion spring coupled to the outer housing and configured to provide radial pressure on the outer housing to receive the conical protrusion of the actuator adapter plug and latch onto the peripheral groove.

A through bolted connection hardware includes a bolt having an at least partially threaded shaft and a head. At least one nut connector defines a shaft hole and a head hole that is coaxial with the shaft hole, and the shaft hole is sized to receive the shaft of the bolt and not to allow the head to fit through the shaft hole. An outer surface of the at least one nut connector has a hexagonal shape. A tube defines an axially extending threaded bore that is configured to matingly receive the shaft at a first end of the threaded bore.

A toggle fixing with two obliquely arranged compression elements which enter into engagement with a screw thread of a screw passed through a screw hole and provide triangular support for the screw. A tension element absorbs compressive forces of the compression elements.

A universal locking pin can be inserted in a through hole for connecting a wide variety of objects. Once engaged in a through hole, the universal locking pin can function as mounting point for attaching items. Materials can be mounted to the attachment hole such as rope or carabiners, cords, rings, and other materials with suitable tensile strength. The locking pin can be scaled up or down in size and constructed from a variety of materials including metal, plastic, wood, ceramic, composites, and the like.

Provided are wall anchors including an external plate and an inside plate partially overlapping the external plate, each of the external plate and an inside plate having a wall-facing side, the plates being rigidly connected to one another adjacent a first end of their respective wall-facing sides by a cylindrical connecting member; at least a portion of the cylindrical connecting member is configured with a round perimeter. Further provided are modifications of such wall anchors.

A holder is provided to be used with a fastener that includes a pivot nut. The holder includes a flange plate, and a pair of substantially U-shaped arm plates disposed on respective opposite sides of the flange plate. The arm plates hold the pivot nut so that the pivot nut is pivotable and movable relative to the flange plate. The flange plate has a threaded member insertion hole through which a threaded member is inserted. The two arm plates are arranged at different distances from the center axis of the threaded member insertion hole.

A fastener for securing a first object to a second object includes a push member, a rigid shaft, an engaging member, a biasing member, and an anchor. The push member and the anchor are fixed to opposite ends of the rigid shaft. The engaging member is slideably coupled to the rigid shaft between the push member and the anchor. The biasing member is disposed between the push member and the engaging member to urge the engaging member toward the anchor. In a particular embodiment, the anchor is deployable.

A device, system and method to connect a receiving member and a connecting device with a pin such that an asymmetrical configuration after the alignment of the connecting member and the receiving member does not give rise to asymmetrical glue distribution, nor asymmetrical shrinking nor curing drift. The receiving member has a receiving planar surface with at least one opening, and the connecting device has a main body with a contact plane, the main body having at least one opening where the connecting device is placed with the contact plane towards the receiving planar surface so that the at least one opening of the connecting device overlaps the at least one opening of the receiving surface, and the pin is inserted into the overlap. The system having a device for exerting a force between the contact plane of the connecting device and the receiving planar surface of the receiving member.

A coupler for removeable coupling an object to a support. The coupler includes a cover, a ring, and a base. The cover couples to the support. The ring includes a first arm, a second arm, a third arm, a fourth arm, a first stop, and a second stop. Each arm of the ring is formed of a resilient material. The ring is positioned in a cavity of the cover. The base couples to the accessory. The base cooperates with the cover and the ring to couple to the cover and to rotate from a decoupled position to an intermediate position and further to a clocked position.
