What type of fasteners are anchor bolts?

Anchor bolts are classified as heavy-duty fasteners because they are specifically designed to secure structures to concrete and other robust materials. These bolts are used to anchor various types of construction elements, such as structural steel, machinery, and other loads, ensuring stability and resistance against forces, including tension, shear, and seismic activity.

Their construction typically involves high-strength materials that can withstand significant loads, making them suitable for permanent installations in heavy-duty applications. This distinguishes them from lightweight connectors, which are more appropriate for non-structural applications, and temporary fasteners, which are designed for short-term use and often lack the durability required for heavy loads. Standard screws, while useful in various applications, do not possess the specific strength or structural capacity necessary for anchoring heavy items effectively. Hence, anchor bolts are properly categorized as heavy-duty fasteners due to their purpose and construction.
