Dril-Flex Structural Screws are dual heat treated self-drilling tapping screws that provide the strength, ductility and resistance to embrittlement required for critical applications.
Features
- High-hardness point and lead threads for drilling and tapping
- Lower-hardness load bearing area provides increased resistance to Hydrogen-Assisted Stress Corrosion Cracking when compared to case hardened fasteners
- Stalgard® and Stalgard® SUB Coatings provide improved corrosion resistance as well as enhanced galvanic compatibility in dissimilar metal applications, including those involving aluminum, compared with fasteners with standard zinc plating
- Fasteners coated with Stalgard® SUB typically show no red rust or other base metal corrosion onsignificant surfaces after 2000 hours of salt spray exposure in accordance with ASTM B117
- Fasteners coated with Stalgard® typically show no red rust or other base metal corrosion on significant surfaces after 1000 hours of salt spray exposure in accordance with ASTM B117
