Description
Dril-Flex self-drilling structural screws are manufactured by DeWalt/Elco. Thes fasteners are commonly used in aluminum to steel connections, aluminum to aluminum connections, or steel to steel connections. The fastener exhibits properties similar to SAE Grade 5 in load bearing area of fastener.
• 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
• Stalgard® and Stalgard® SUB Coatings provide improved corrosion resistance as well as enhanced galvanic compatibility in dissimilar metal applications, including those involving aluminum, compared with fasteners with standard zinc plating
• Custom fastener painting is available for all of our self-drilling screws, contact us for painting
Common applications include: dissimilar metal fastening, aluminum to steel, aluminum to aluminum, and curtainwall construction.
