Structural latch assemblies

Structural latch assemblies are used in applications requiring elevated static and dynamic load-carrying capability for larger structures where ease of access for passenger entry, cargo loading, or maintenance is required.

 Hook latches and keeper assemblies offer high reliability and quick access when mounted onto engine fan cowls, fairings or thrust reverser structures. Low profile latches provide ease of closure and can be used in limited access areas. Adjustable hook latches are used in restricted envelopes where an adjustable keeper cannot be installed. The adjustment property offers quick rigging of the latch.

 Rotary latches, available in rotary cam or hook actuated versions, are used where high strength is required in limited space and can be operated using standard hex or square drive tools.

Access door mechanisms

Access door mechanisms provide ease of entry into frequently accessed panels, doors and hatches.
Pressure relief door latches provide controlled, pressurization-sensitive release loads for engine cowls, fairings and thrust reverser doors. We also offer variations such as thick door, high temperature models, flush button, adjustable bolt push button, and heavy or light duty latches.
Push-button latches are available in both one and two-push button designs. The simplified “button” release offers ease of manual operation, facilitating activation if maintenance is performed while wearing heavy gloves.


Hinges are used on a variety of door and panel applications. Gooseneck hinges are used for pressure relief door and for smaller applications such as fuel access doors. Double acting hinges provide additional clearance for restricted areas, where full exposure of the door cavity is required. Hinges are available in both aluminum for light duty applications and in corrosion resistant steel for heavy duty or high temperature applications.

Latch handle systems

Latch handle systems are comprised of various types of mechanisms and provide a means of activating latch systems where access to, or visual contact of the latch mechanism, is limited. Flush handle assemblies are used for cargo, APU or emergency door access.
Remotely operated latching systems are designed for fan cowl, engine fairing and thrust reverser systems.
Multiplepin latch assemblies are used to stow removable or hinged door panels in interior or exterior applications.

Non-structural latches

Pawl latches are designed to secure hinged panels and small doors. To secure the panel or small door, the pawl engages the frame structure through the axial rotation of an actuator that turns a wire-form or solid arm pawl to engage or disengage the latch to allow opening or closing of the small door or panel.

Camloc® tension latches are used to install light to heavy-duty hinged doors, panels, and structures.


Clamps are used for the installation and maintenance of wire bundles, hoses, tubing, cable, and conduits. They provide split-second access to clamped material with accepted proven vibration-resistant, Camloc® 1/4-turns. They are available in hand or tool operated head styles. Some styles have liners that allow positive clamping of material without damage.

Avionics hardware

Chassis latches are offered in a wide variety of styles and strengths. Many are used for removable electronic drawers and can seat multiple-pin connectors or RFI gaskets.
Hold-down devices are designed to secure avionics boxes and modules in a variety of aerospace applications.
Self-compensating injector/ejector levers provide consistent self-compensation for circuit board installation tolerances. With minimal finger pressure, multiple-pin or fiberoptic connections can be seated with controlled forces ranging from 20 to 80 pounds.

Wedg-Tite® retainers lock boards in place without expensive torque wrenches; it uses a simple hex key. It features a built-in torque limiter and provides heat transfer between thermal paths and heat sink. Wedg-Tite® will not crush boards. With only a few pounds of finger pressure, our series of PCB injector/ejector levers provide 10 times that amount of pressure to positively mate PCB connectors. They also lock boards into card cages, preventing disconnects due to shock and vibration. For printed circuit boards, Wedg-Tite® retainers securely fasten while providing heat transfer paths. A stop nut prevents accidental disassembly, and a spring element prevents accidental unlocking.

Hydraulic snubbers

Hydraulic snubber assemblies are used as dampening devices for radome and tailcone applications. The hydraulic fluid-filled cylinder provides for dual speed operation in the opening and closing directions. The tailcone subbers are equipped with a remote lock release mechanism to facilitate closure.

Assembly integration capability

Arconic Fastening Systems also has the capability of integrating our latches, hinges, and other fasteners for customers requiring complete fabrication of their assemblies or sub-assemblies, such as pressure relief doors or other applications.

Specialty latches

Arconic Fastening Systems custom designs are uniquely suited for reliable performance in punishing environments. With design and manufacturing in Torrance, California and Kelkheim, Germany, Arconic Fastening Systems is exceptionally positioned to support the global need for innovative, engineered latching mechanisms as well as avionics hardware product solutions.
