Product Description
The ASSY SK 4.0 are partially threaded high performances structural fasteners. They are ICC-ESR [3179] approved fasteners, designed to pull connection elements tightly together and are recommended when head pull-through is the governing consideration.
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.
