Aircraft precision hardware fittings

Aircraft precision hardware fittings are key components that ensure the safe operation and performance of aircraft. There are various types. 

Here are some common types and their characteristics for you:

High-strength bolts and nuts: Used for the connection of aircraft structures and need to withstand huge loads and vibrations. For example, titanium alloy high-strength bolts have excellent strength and fatigue resistance.

Rivets: Widely used in the connection of aircraft skins and structural components. Common ones are aluminum alloy rivets, which ensure the firmness of the connection while reducing weight.

Precision shaft parts: Such as transmission shafts, crankshafts, etc., require extremely high precision and surface quality to ensure the accuracy and reliability of the transmission.

Aviation plugs and sockets: Used for the connection of aircraft electrical systems and have good conductivity, sealing and anti-interference capabilities.

Locks and fasteners: Such as cabin door locks, luggage compartment fasteners, etc., to ensure the safe closing and fixation of various parts of the aircraft.

Hydraulic pipe fittings joints: Transmit pressure in the aircraft hydraulic system and must have the characteristics of no leakage and high pressure resistance.

Pulleys and rollers: Used for the movement and guidance of aircraft cabin facilities, such as the sliding parts of luggage racks.

When choosing aircraft precision hardware fittings, special attention needs to be paid to the following factors:

Material performance: Materials such as titanium alloys, aluminum alloys, and stainless steel, which are usually high-strength, lightweight, high-temperature resistant, and corrosion-resistant, are often used.

Precision requirements: The dimensional accuracy and geometrical tolerance of fittings often need to reach the micron level to ensure the accuracy and reliability of assembly.

Quality certification: It must comply with the strict quality standards and certification systems of the aviation industry, such as AS9100, etc.
Reliability and durability: In harsh flight environments, it can work stably for a long time and has a very low failure rate.

Some well-known suppliers of aircraft precision hardware fittings include Parker Hannifin from the United States, Safran from France, etc.
