Product Description
The A2 Stainless Steel Ecofast are high corrosion resistant structural fasteners suitable for use in wet service conditions & corrosive environments. These ICC-ESR approved fasteners are designed to reduce wood splitting during installation. They offer a precise setting without the need for pre-drilling (may be recommended for long models).
Made from chromium-nickel austenitic stainless steel (corrosion resistant) with low carbon content and copper addition. Considered to be equivalent to 304 stainless steel.
ASSY screws may also contribute to LEED 5.0 certification with up to 6 points, thanks to their Environmental Product Declaration (EPD) (available upon request) and recycled content.
