What are the different types of aircraft fasteners?
Common fasteners used in the aerospace industry include the following:
- Anchors.
- Locking Bolts.
- Hex Bolts.
- Collars.
- Security Screws.
- Hex Nuts.
- Pins.
- Rivets.
What are aerospace fasteners?
The aerospace industry employs a variety of standard fasteners, including screws, rivets, nuts, bolts, pins, and collars.
What are NAS bolts?
NAS bolts comply with the National Aerospace Standard and are commonly used for high technology systems. NAS bolts are necessary for high strength applications and consist of a fine-threaded, dimple headed hex bolt. Material markings for NAS bolts are the same as AN bolt, except they may be either raised or recessed.
What are aerospace fasteners made of?
Commonly Used Fasteners in the Aerospace Industry Aircraft bolts: These are made of unplated corrosion-resistant steel, zinc plated corrosion-resistant steel, cadmium, or anodized aluminum alloys. Moreover, the commonly used bolts for aircraft are MS bolts, close tolerance bolts, NAS internal wrenching, and AN bolts.
What is a turnlock fastener?
Turnlock fasteners are used to secure inspection plates, doors, and other removable panels on aircraft. Turnlock fasteners are also referred to by such terms as quick opening, quick action, and stressed panel fasteners.
What are special fasteners?
Special fasteners are a bolt used under industrial circumstances to hold pieces heavy weight industrial components together under extreme pressure. These screws are made out of materials highly resistant to corrosion. This is necessary because of the type of equipment they are expected to hold together.
Which type of rivet is used in aircraft industry?
Cherry “Q” rivets have limited structural use. They do provide a high shear strength. A number of kit manufacturers use the Cherry “Q” type rivet in the construction of their aircraft. Rivnuts are another type of blind rivet.
How are aircraft bolts measured?
The length of AN aircraft bolts is measured from under the head to the end of the shank. The “grip” is the unthreaded portion of the shank.
What is difference between NAS and an bolts?
The NAS bolts are stronger than AN bolts. The NAS are about 160,000psi (tensile) vs. about 125,000psi for the AN bolts. I NAS bolts are optional for ski installation otherwise you can use AN hardware on the axles.
What does NAS stand for in hardware?
Network-attached storage (NAS) is a file-level storage architecture that makes stored data more accessible to networked devices. NAS is 1 of the 3 main storage architectures—along with storage area networks (SAN) and direct-attached storage (DAS).
How do you identify aircraft hardware?
Aircraft hardware is usually identified by its specification number or trade name. Threaded fasteners and rivets are usually identified by AN (Air Force-Navy), NAS (National Aircraft Standard), and MS (Military Standard) numbers.
