HSFG bolts are commonly used in structures that will be exposed to a lot of vibrations, or loadings that will reverse. Since the bolts are preloaded the tension in the bolt doesn’t vary as much as in a standard bolt, so they don’t fatigue as quickly. They also will prevent any slip between the plates, which means your fastener won’t come loose.
