Elco’s Dril-Flex Self-Drilling Structural Screws represent a dual heat-treated innovation in self-drilling tapping screws, designed to meet the stringent requirements for strength, ductility, and resistance to embrittlement in critical applications. These screws are commonly employed in various applications, including curtain walls, rainscreen systems, window walls, glazing, solar panel installations, architectural guardrails, and more.
The notable features and advantages of Elco Dril-Flex screws include:
-
High-hardness point and lead threads tailored for efficient drilling and tapping.
-
Lower-hardness load-bearing areas, ensuring heightened resistance to Hydrogen-Assisted Stress Corrosion Cracking when compared to fasteners with case-hardened properties.
-
Stalgard® and Stalgard® SUB Coatings, enhancing corrosion resistance and galvanic compatibility in dissimilar metal applications, particularly with aluminum, surpassing the performance of fasteners equipped with standard zinc plating.
-
Fasteners coated with Stalgard® SUB typically exhibit no red rust or other base metal corrosion on significant surfaces after 2000 hours of salt spray exposure, as per ASTM B117 standards.
-
Fasteners coated with Stalgard® typically demonstrate no red rust or other base metal corrosion on significant surfaces after 1000 hours of salt spray exposure, following ASTM B117 guidelines.
