The A325 specification includes various criteria that these fasteners must meet, such as mechanical properties, dimensional tolerances, and testing procedures. One of the critical attributes of A325 bolts is their ability to withstand significant tension and shear forces, making them ideal for applications in bridges, buildings, and other infrastructure projects.

Self-drilling screws, often referred to as Tek screws, are specialized fasteners that possess a unique drill point. This drill point enables the screw to create its own hole in the material, eliminating the need for pre-drilling. When combined with the galvanized coating, which provides excellent corrosion resistance, these screws become ideal for outdoor and high-humidity environments.

Metal expansion nuts find their usage in diverse fields. In construction, they are frequently employed for securing structural elements, like beams and frames, in concrete. They are also prevalent in HVAC systems, where they help secure ducts and other installations prone to thermal expansion.
