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
- Wood-to-steel connections

APPROVALS
- International Code Council, Evaluation Service (ICC-ES), ESR-3332
- International Code Council, Evaluation Service (ICC-ES), ESR-4367
- Code compliant with the International Building Code/International Residential Code: 2018 IBC/IRC, 2012 IBC/IRC, and 2009 IBC/IRC
- Tested in accordance with ICC-ES AC118 for use in Steel-to-Steel Connections
- Tested in accordance with ICC-ES AC500 for attaching Miscellaneous Building Material to Steel
