Dril-Flex Structural Self-Drilling Fasteners 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.
