What should be visually examined before the installation of high tensile bolt connection components?

Visual examination of high tensile bolt connection components before installation is crucial for ensuring safety and integrity in structural applications. Damage and corrosion can significantly impair the performance of these bolts. If a bolt shows signs of wear, such as surface cracks, deformation, or rust, it may not perform as intended under load, leading to potential failure of the connection.

Identifying any damage or corrosion before installation allows for the timely rejection of compromised components, thereby maintaining the strength and reliability of the entire structure. This preventive measure reduces the risk of accidents and structural failures once the assembly is put into service.

While other elements like color coding, specifications, and the manufacturer's manual can inform about the intended use and requirements for the bolts, they do not address the condition of the bolts themselves. Therefore, focusing on damage and corrosion is paramount to ensure that only safe and reliable components are utilized in the construction process.
