2. Vibration and Dynamic Loads Structures exposed to vibrations, such as bridges and industrial facilities, are particularly susceptible to loose anchor bolts. During the operational phase, vibrations from machinery, traffic, or environmental factors can gradually loosen bolts over time.

Wing Tek screws are a specialized type of fastener that features a unique wing design. This innovative design allows for greater torque and grip compared to standard screws, making them ideal for tasks that require a secure hold. The wings, which extend from the body of the screw, serve a dual purpose they facilitate easier installation and enhance the screw's overall performance. By providing a larger surface area to grip, they ensure that the screw can be tightened more effectively without slipping or stripping.

In the United States, ASTM (American Society for Testing and Materials) standards define the specifications for shear studs. For instance, ASTM A108 has specifications for carbon steel shear studs, which are often used due to their strength and ease of welding. The tolerances for size are usually specified to ensure consistency in performance and reliability in construction.
