Product Description
The ASSY FWH 4.0 are partially threaded high performances structural fasteners. They are ICC-ESR [3179] approved fasteners, designed to pull connection elements tightly together.
They are two-in-one engineered screw that combines the pulling power of a washer-head screw with the clean finish of a countersunk head screw. Their design offers a precise setting without the need for pre-drilling (may be recommended for long models). Their blue passivated zinc coating makes them adequate for use in low corrosive environment, such as dry service condition. 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.
