Dril-Flex screws are engineered and processed to help prevent hydrogen-induced brittle failures. Each fastener undergoes the unique Flex Technology® dual-hardening process, ensuring the optimal combination of ductility and hardness required for maximum performance in the field. Stalgard® coating provides additional corrosion resistance. Testing of this product, in accordance with ASTM standards, has proven that Dril-Flex screws provide the same resistance to hydrogen-assisted cracking (HAC) as a Grade 5 screw. Virtually immune to delayed embrittlement failures
Precision-engineered and dual heat treated drill screws provide the strength, ductility and resistance to embrittlement required for critical applications. Elco Dril-Flex self-drilling screws meet the same construction specifications Hilti Kwik-Flex
