Developing airplanes is a precise business and it requires a lot of experience in construction and design. In most cases, one person or specialist handles one area of design or construction, meaning multiple people may work on one specific aircraft. This means that each person must be the best in their field and can pay attention to the minutest details.
In order to have the best built plane, you must have the best materials. Whether you need the upholstery for the inside or the tiniest screw or bolt, you need to have the best. NASM (National Air and Space Museum) fasteners are the best because they have the highest standards around. Fasteners and nuts/bolts are usually called Aerospace hardware and require many thousands of these hardware resources to create a completed aircraft.
The fasteners generally match up or come in automated sets that can save you money, but ultimately, they must be of the best quality.
The material is usually made of titanium or steel and they are meant to provide stability and power wherever they are placed. This means these hardware fasteners are usually placed in key portions of the airplane to ensure quality and strength throughout.
The term fatigue strength is used to describe the sturdiness and safety of the framework. If you have a poorly built frame, you will have a poorly built airplane, which is unsafe. For this reason, aircraft hardware has set standards that must be met before they can be used. The standards indicate finish, measurements and tolerance. Mostly, alloy 600 and titanium are used.
Titanium is very light, but sturdy while alloy 600 can be used in areas that need heavy duty strength and application.
NASM fasteners are developed for the standard of Smithsonian Institution collections of historical space and aircrafts. These fasteners can be used on newer models, but are considered safe to be used on historical pieces that offer beauty and awe-inspiration.
Other options include NAS (national Aerospace Standard), AN (Army Navy) standard, and MS (Military Standard). Each of these fasteners are multi-purpose in nature and require parts from the authorized dealers. For more information visit http://www.fastenerdimensions.com/fasteners.html
