Product Description

Product Description

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