Another compelling advantage of self-drilling screws is the secure fastening they provide. The design of these screws allows for a strong bond between materials, ensuring that connections hold up over time. The 2-inch length is particularly useful for thicker materials or applications requiring additional grip. The deep threads and robust shaft of these screws help enhance their load-bearing capacity, making them an excellent choice for high-stress applications.

- Drive Type Tek screws come with different head styles and drive types, such as Phillips or hex. Choose a drive type that is compatible with your tools for efficient installation.

The body of a hex head bolt features external threads that engage with a corresponding nut or a tapped hole, allowing for a secure and adjustable connection. Depending on the intended application, these bolts can be made from various materials, including steel, stainless steel, and even plastic, each offering different levels of strength, corrosion resistance, and weight considerations.

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.
