Applications of Wafer Head Screws

The term 2% self-drilling screws generally refers to a specific classification or standard that adheres to a manufacturing specification, often denoting the composition or performance traits of the screws. The 2% might relate to various factors such as the percentage of alloying elements in the material, or guidelines that measure performance under certain conditions. For instance, these screws might contain 2% alloying elements that enhance their strength and corrosion resistance.

Self-drilling screws, also known as Tek screws, are fasteners that can drill their own pilot holes as they are being installed. This feature eliminates the need for pre-drilling, significantly reducing assembly time and effort. Their design typically incorporates a drill point, which allows the screw to penetrate hard materials, including metal and wood, without additional tooling.

The terms 3% and 4% often relate to the percentage of the anchor bolt’s yield strength in relation to the concrete’s compressive strength. For example, a 3% concrete anchor bolt means that the bolt can withstand loads up to 3% of the concrete's yield strength, while a 4% bolt can handle loads up to 4%. This distinction is vital for engineers and contractors, as it influences load calculations, safety factors, and the overall design of the structure.

Heavy-duty expansion anchors are used in a wide array of applications, including

3. Stud Spacing The spacing between shear studs is equally important. The spacing is typically determined by the applied load and the design code requirements. Standard practice suggests a spacing that ensures a uniform distribution of loads across the beam.

2. Strength and Reliability These screws provide exceptional holding power, making them ideal for securing roofing panels against strong winds and other environmental challenges. Their design ensures a tight fit, which minimizes the risk of loose roofing materials over time.

There are different types of Tek screws designed for various applications. Some of the most notable types include

2. Automotive In the automotive industry, these bolts can be found securing body panels, engine components, and various assemblies. Their reliability and strength are key factors in ensuring vehicle safety and integrity.

3. Ease of Use The self-drilling feature simplifies the installation process. Users do not need to purchase or use a separate drill bit for pilot holes, making them a convenient choice for both professional contractors and DIY enthusiasts.
