If you’re looking for the most common aircraft fasteners, you’ve come to the right place. First, learn about NAS bolts, Airloc panel fasteners, Turnlock fasteners, and Aluminium alloys. Ultimately, you’ll know how to find the top fastener distributors for your airplane.

Turnlock fasteners

Turnlock aircraft fasteners are common types of aircraft hardware. They secure removable panels to aircraft and are referred to as quick-open, quick-action, and stressed panel fasteners. They are often made by different manufacturers and sold under different trade names. The most common types of turnlock fasteners are the Dzus, Camlock, and airlock types.

A turn-lock aircraft fastener has a shank and button with a tubular bore and spiral bayonet slots. The button’s shank receives the stud and has holes for the spring (22). The slotted shank holds the cross pin in the closed position. Turnlock fasteners are typically made from high-carbon steel.

NAS bolts

NAS bolts are high-strength, close-tolerance bolts used in aerospace applications. For example, the NAS1307-50 attaches the plane’s wing structure to the main body. This bolt is known for its smaller thread pitch and higher tensile strength than standard AN7 bolts.

These aircraft fasteners are characterized by their high tensile strength and intelligent design. These bolts have fine threads and are manufactured to meet strict specifications. Their threaded heads are marked with raised and recessed markings. They can also be made from stainless steel or other alloys to ensure durability. If you need a bolt made to withstand extreme temperatures and rigorous usage, NAS aircraft fasteners are an excellent choice.

Airloc panel fasteners

The fastener used to secure access panel covers in an airplane is called an Airloc. They come in two types: floating and fixed. The floating version is easier to install, while a cross pin secures the revised version. The Airloc fastener consists of a cross pin and a stud. The cross pin is riveted to the access panel frame. Both types are made of carbon steel and have different construction features.

Aluminum alloys

Researchers from NUST MISIS, in collaboration with RUSAL’s Light Materials and Technologies Institute, have developed an aluminum alloy that is tough and slender. Shortly, additive manufacturing can replace conventional casting methods, producing highly detailed parts with the same properties without requiring a high-tech process. The primary additive manufacturing method is selective laser melting (SLM). Aluminium-silicon alloy components manufactured with SLM show high strength at room temperature, although they often fail at temperatures higher than 200 degrees Celsius.

Alloys for aircraft fasteners are commonly made of Alloy 2014, which is known for its high strength and high toughness. This alloy is non-sparking and odorless and is widely used inside the shell and framework of aircraft. It is also suitable for arc welding. Another alloy used for aircraft fasteners is Alloy 2024. This grade of alloy has high strength and flexibility and can be welded into various shapes and forms.


In terms of price, titanium aircraft fasteners vary widely. Costs vary significantly depending on their diameter and length. The primary factor determining price is the amount of hardware used by commercial entities and the military. Large-diameter parts tend to be cheaper, but prices can fluctuate substantially.

Aerospace manufacturers increasingly use lighter materials for their aircraft, and fasteners are no exception. AirbusA380 and BoeingB787 both use more titanium than any other aircraft. The military aerospace industry consumes the most titanium, though. These aircraft, which include the F/A-18, C-17, and UH-60 Black Hawk helicopters, all have lighter structures. In addition to their weight savings, these aircraft have higher operational efficiencies.
