Dril-Flex® Structural Self-Drilling Screws

Virtually Immune to Delayed Embrittlement Failures

Dual heat treated drill screws provide the strength, ductility and resistance to embrittlement required for critical applications.

  • Stalgard SUB coating (Hex washer product only) provides 2000 hours of salt spray resistance (per ASTM B117)
  • High-hardness points and lead threads for drilling and tapping with lower-hardness in load-bearing threads for ductility
  • Virtually immune to delayed embrittlement failures

Approvals

  • ICC-ES Report No. ESR-3332
  • COLA (City of Los Angeles) Research Report #25095
