Elco Dril-Flex Structural Hex Washer Head Self-Drilling Screws: #12-14 x 3, #3 Point

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
