What precaution should be taken when selecting bolts for high-strength applications?

In high-strength applications, it is crucial to ensure that the bolts selected are appropriately graded for the application. This involves choosing bolts that are designed to withstand the specific loads and stresses that will be encountered in service. High-strength bolts are categorized by their grade, which specifies their tensile strength, yield strength, and other mechanical properties relevant to their performance in structural applications.

Using appropriately graded bolts ensures that they have been formulated to meet the necessary safety and performance standards. It also helps to prevent failure due to inadequate strength or improper material composition, which can have serious consequences in structural integrity.

Locally sourced materials, visual inspection alone, and the belief that standard sizes suffice may lead to inappropriate bolt selection, thereby compromising the design and safety of the structure. Each application may require specific grades and materials to ensure proper functioning and compliance with building codes and engineering standards.
