Dril-Flex Structural Drill 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 enhanced galvanic compatibility in dissimilar metal applications
- Fasteners coated with Stalgard SUB finish typically show no red rust or other base metal corrosion on significant surfaces after 2000 hours of 5% neutral salt spray exposure (per ASTM B117)
- Fasteners coated with Stalgard finish typically show no red rust or other base metal corrosion on significant surfaces after 1000 hours of 5% neutral salt spray exposure (per ASTM B117)

APPLICATIONS
- Steel-to-steel connections
- Aluminum -to-steel connections
- Aluminum-to-aluminum connections
