Technical Usage
These screws are specifically engineered for fastening steel purlins, where precision and strength are critical. The self-drilling feature eliminates the need for pre-drilling, reducing installation time and effort. The rubber washer provides an effective seal, preventing water ingress and ensuring structural integrity in applications exposed to weather elements. They are widely used in roofing, cladding, and steel structure assemblies.

History
The development of these screws stems from the need for efficient and reliable fastening solutions in modern construction. With advancements in coating technology, tetanized screws became a preferred choice for their exceptional rust resistance and ability to withstand extreme conditions. The addition of rubber washers enhanced their functionality by providing better sealing and vibration dampening, solidifying their role in steel structure assembly.
