Features
- 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
- 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
