Airframe Bolt Identification
Airframe Bolt Identification. When building an aircraft, the right equipment and hardware is vital. Without them, you risk serious damage and problems that put your life in danger. This could result in malfunctions, damage, and failures that force you to ground the plane, sometimes in dangerous situations. This is avoidable if you make sure that what is used from the start is quality and capable. For bolts and other small pieces, you have to consider more than size and purpose. Not all are made equally and poor quality parts may result in higher chances of destruction. To ensure that you are choosing the one that is right for you, you have to know how to identify them and how to choose the best one for the job you need done.
Search For Bolts
Every part of the airframe bolt matters. At the top, you have the hex head. For those who may not know, not all are the same. As you study each, you will see several differences that help you to identify each of them. There are many out there and choosing the right one might rely on knowing these differences.
Bolt, Close Tolerance
The one thing that you are always going to want to look out for is AN. An AN bolt means that it is manufactured to the specifications of the Air Force / Navy. If it is not, you are risking damage and serious issues. Even if you are not building for the Air Force or Navy, you should want to hold your standards just as high. This is an aircraft that will be in the air, so making sure that it is held to high standards is vital.
You will also find letters, numbers, and other additions on the hex head. Each one means something different, like 4 indicating size, so you should know what you need. When you know the size and type, look through the list of bolt hex heads to see which one matches your needs. Just remember to make sure that it is an AN bolt. If it is not, you are putting quite a bit at risk, as stated above.
Below the head, you have the thread and the grip. Make sure that you know which kinds you need, like drilled or undrilled as well as material, since these are the parts going into what you are building. If they are not quality or suitable, they may not work. As stated, you can find out more about the bolt by looking at the head. This will tell you material, size, and all other necessary information.
When looking into fasteners, you need to buy the best one. Without prior knowledge of what you are buying, you may choose something poor quality or unsuitable. Luckily, there is a very easy way to indentify bolts. Your first step is going to make sure that it is an AN bolt, which means that it is Air Force / Navy approved. You should then make sure that you carefully read the hex head to see the exact specifications. This will tell you size, material, and more, giving you the information that you need.
