Aircraft structural fasteners come in various forms, including bolts, nuts, rivets, screws, and pins. Each type of fastener is designed to perform a specific function, whether it's providing a secure connection between two parts or allowing for easy disassembly and reassembly of components for maintenance and repairs. These fasteners are typically made from durable materials such as stainless steel, titanium, or aluminum, which are chosen for their strength, corrosion resistance, and lightweight properties.

Moreover, the foundation bolt's design also considers the stability and alignment of the cartridge in the chamber. A precisely engineered bolt ensures that each round is fed smoothly, providing consistent performance in rapid-fire scenarios. The interplay between the bolt and the gas system is another critical aspect of the M16's design. The gas piston system harnesses the energy created when the rifle is fired, cycling the bolt backward to eject the spent casing and chamber a new round. This gas operation is not only efficient but also significantly reduces recoil, making the M16 easier to control and more accurate in the hands of its shooter.
