The choice of materials in bolt construction is paramount as it directly influences the strength and durability of the component. Common materials used for bolts include high-carbon steel, stainless steel, and alloy steel, each offering different mechanical properties to suit specific environments. For example, stainless steel bolts exhibit excellent corrosion resistance, making them ideal for applications in maritime environments and industries that handle corrosive substances. In contrast, high-carbon steel bolts offer enhanced tensile strength, which can be critical for high-stress applications.

Self-drilling screws, as the name suggests, eliminate the need for a pre-drilled hole, saving significant time and effort in construction, manufacturing, and repair projects. The flat head design of these screws is particularly advantageous as it sits flush with the surface, providing a clean and aesthetic finish. This feature makes them ideal for applications where a smooth surface is crucial, such as in furniture making, automotive repairs, or electronics assembly.

Tek screws, a brand name associated with self-drilling screws, are designed for quick and efficient assembly without the need for pre-drilling, which significantly reduces labor costs and time on job sites. The 13mm wafer head variant is characterized by its unique flat, wide head that provides a larger bearing surface. This design not only helps in distributing the load evenly across the material but also minimizes the risk of surface damage, making it ideal for use in visible applications.
