Product Description

Product Description

The ASSY Kombi 3.0 are partially threaded high performances structural fasteners. They are ICC-ESR [3179] & CCMC approved fasteners, designed to pull tightly together connection elements in steel-to-wood configuration.

 

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.
