Structural fasteners are essential components used to join or secure various parts of a structure, such as buildings, bridges, and machinery. Common types of structural fasteners include bolts, nuts, washers, and screws. These fasteners provide strength and stability, ensuring that the connected elements can withstand loads and forces. The selection of appropriate structural fasteners depends on factors like the materials being joined, the environment, and the required load capacity. Proper installation and maintenance of these fasteners are crucial for the safety and longevity of the structure. Regular inspections can help identify any wear or damage that may compromise structural integrity.
