What is a typical characteristic of high-strength bolts?

High-strength bolts are specifically designed to provide a stronger connection in structural applications. This strength is essential when dealing with heavy loads and significant structural demands, such as in bridges, buildings, and other engineering projects. The unique composition and heat treatment processes involved in producing high-strength bolts enhance their tensile and shear strength, allowing them to withstand greater forces without failing.

While it is true that high-strength bolts can be reusable under certain circumstances, their primary characteristic that sets them apart from standard bolts is their ability to create a strong, reliable connection. The other options either do not accurately describe high-strength bolts or are not defining characteristics, which emphasizes why the strength attribute is critical in their application. Coatings may be present for corrosion resistance but are not a standard feature of every high-strength bolt.
