White wafer head self-drilling screws are commonly used in a range of applications, particularly in metal roofing and siding installations. Their ability to create a secure and weather-tight seal makes them ideal for exterior applications where moisture ingress could lead to structural damage. Additionally, they are often employed in HVAC (heating, ventilation, and air conditioning) installations, where metal framing and ductwork require reliable fastening solutions.

2. Weight Reduction In industries such as aerospace and automotive, weight is a critical factor. Bonded fasteners allow for the elimination of heavy mechanical fasteners and their associated components, leading to overall weight savings. This not only enhances fuel efficiency but also contributes to improved performance of the final product.
