Hex head bolts are a type of fastener characterized by their six-sided (hexagonal) head, which allows for easy gripping and torque application using a wrench. Typically made from materials like carbon steel, stainless steel, or alloy steel, these bolts come in various sizes and grades, each designed to meet specific strength and durability requirements. The hexagonal shape of the head provides a larger surface area for handling, making it easier to achieve the necessary clamping force when tightening.

Conclusion

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.

2. Expansion Screws These screws are designed for concrete or masonry walls. When installed, they expand and grip the surrounding material as the screw is driven into it, creating a robust anchor point.

Another significant benefit is the strength and durability of these screws. Galvanized screws are well-known for their ability to withstand harsh weather conditions. This makes them particularly suitable for applications in construction, such as metal roofing, wood-to-metal fastening, and other structural assemblies. The self-drilling feature also ensures a strong bond, as the screw is driven directly into the material without the risk of splitting or damaging it.
