The design of a bolt structure also involves careful consideration of its mechanical properties, such as tensile strength, shear strength, and fatigue resistance. Tensile strength refers to the maximum load a bolt can withstand while being pulled in tension, whereas shear strength is associated with the load bearing capacity when the bolt experiences forces perpendicular to its axis. Fatigue resistance is particularly important in structures subjected to repeated loading cycles, as it ensures that the bolt can withstand the wear and tear of regular operation without failure.

The fully threaded rod 1/4, as the name suggests, is a long, slim rod with threads running along its entire length. The diameter of the rod measures a quarter of an inch, hence the 1/4 designation. These threads are typically standardized, ensuring compatibility with a wide range of nuts and accessories. Made from durable materials such as stainless steel or brass, these rods are built to withstand significant force without yielding or breaking.
