Evolution Fasteners’ screws are manufactured in two production facilities in Jiangsu and Zheijang, China. This EPD refers to screws made in both facilities, and is based on the LCA results of the “worst case” of these two production facilities. The high-quality self-tapping fasteners designed for efficient and reliable fixing across various applications, including steel, timber, board, and masonry. These screws are ideal for single-sided assembly operations, eliminating the need for pre-drilling and reducing labor time. They are commonly used in roofing, cladding, timber sheets, board materials, and lightweight construction methodologies. Their versatility makes them suitable for securing metal profiles or other fixture materials to substrate structures. The screws are engineered to provide long-term stability, pull-out resistance, and load-bearing capacity, ensuring structural reliability and aesthetic quality. They are available in diverse geometries, drive types, and protective finishes, allowing contractors to select solutions tailored to specific project demands.
