Product Description

Product Description

The ASSY Kombi 4.0 are partially threaded high performances structural fasteners. They are ICC-ESR [3179] approved fasteners, designed to pull connection elements tightly together in steel-to-wood configurations. 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.
