Study Notes
Aircraft Fasteners
- The term used to describe various types of fasteners and miscellaneous small items used to manufacture and repair aircraft is not specified in the provided text.
Bolts and Screws
- Bolts and screws are classified as threaded fasteners.
- Bolts are typically used in structural applications where high strength and resistance to vibration and shear are necessary.
- The deciding factor for using screws is that they provide a simple and efficient way to assemble components.
Bolt Identification and Specifications
- A nut is usually screwed onto the threaded end of a bolt to complete the assembly.
- The standard thread for 1-inch diameter size bolts with 14 threads is not specified in the provided text, but it is unified national coarse (UNC).
- Military Standard Bolts (MS bolts) have a minimum tensile strength of 125,000 psi.
- AN Bolts can be composed of either steel, cadmium-plated steel, or corrosion-resistant (stainless) steel.
Close Tolerance NAS Bolts
- Close Tolerance NAS Bolts can be identified by the "NAS" prefix in the part number.
- The distinguishing feature on the head of a corrosion-resistant (stainless steel) bolt is a circle around the "R" in the marking.
Bolt Identification and Usage
- When the letter 'H' precedes the '5' in the identification of a bolt, it indicates a heavy bolt.
- A bolt identified as AN3DD5A is expected to be used in an application requiring high strength and resistance to vibration and shear.
- Close Tolerance Bolts are used in critical structural applications where high strength and resistance to vibration and shear are necessary.
Additional Information
- It is not recommended to use aluminum alloy nuts with cadmium-plated steel bolts on land airplanes because of galvanic corrosion concerns.
- Threads for 1-inch diameter size bolts with 12 threads are classified as unified national coarse (UNC).
