Product Description
The ASSY FWH 3.0 are partially threaded high performances structural fasteners. They are ICC-ESR [3179] approved fasteners, designed to pull tightly together connection elements.
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. They participate in LEED BD+C 2.0 certification [MRc 4.1 & 4.2, 2 points possible] thanks to the percentage of post-consumer recycled steel used to manufacture them.
