What is essential to verify before using fasteners in structural applications?

In structural applications, verifying the dimensions and specifications of fasteners is crucial to ensure their proper fit and functionality. Fasteners must meet strict engineering standards to withstand the loads and stresses they will encounter in service. This includes checking factors such as thread size, material type, tensile strength, and corrosion resistance, which are all determined by the specifications outlined in the engineering documentation.

Using fasteners that do not meet these specifications can lead to structural failure, safety hazards, or performance issues. For example, if a fastener is too short or has the wrong thread pitch, it may not secure components properly, leading to joint failure. Therefore, confirming that the fasteners adhere to the required dimensions and specifications is essential to maintaining the integrity and safety of aviation structures.
