expanding concrete anchor bolts

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.

The terms 3% and 4% often relate to the percentage of the anchor bolt’s yield strength in relation to the concrete’s compressive strength. For example, a 3% concrete anchor bolt means that the bolt can withstand loads up to 3% of the concrete's yield strength, while a 4% bolt can handle loads up to 4%. This distinction is vital for engineers and contractors, as it influences load calculations, safety factors, and the overall design of the structure.
