Red Rock Distribution Znal Zinc/aluminum Capped Screw

Red Rock Distribution introduces Znal, a revolutionary zinc/aluminum capped screw with an innovative patent-pending design that will transform the world of fasteners as we know it. Designed for speed and productivity far beyond competitor products, it’s the smart buy for contractors and manufacturers focused on top quality and the bottom line.

Znal’s nick tip enables a proven cutting speed .59 seconds faster per screw than the best available competitor, dramatically improving productivity on the job site. Our time study resulted in Znal drill time of 2.98 seconds vs. 3.57 seconds for the closest competitor.

It also reduces waste due to the cap design, which is firmly attached to multiple points on the body of the screw, including under the bearing surface as well as onto the hex head of the body of the screw.

“Imagine the labor savings you could realize over the next year by switching to Znal,” said Kyle Clark, president of Red Rock Distribution. “We thoroughly tested Znal through an independent laboratory to ensure its quality, and I am excited to introduce this clearly superior fastener to the North American market.”

Znal is stronger than most commercial fasteners due to the cap’s composition of Zamak 5 or Zinc Alloy 5 with a higher copper content, which is stronger than the standard Zamak 3 used in other products’ caps. The indented cap seats properly with all major brands of hex driver bits, which will reduce “walking” of the fastener, further increasing productivity.

Znal is available in #12 and #14 diameters from 7/8” – 2-1/2” in length. Other sizes may be available for specific applications. It is ideally suited for the construction industry, including metal buildings, wood buildings, self-storage units, pole barns, decks and many other jobs.

It is sold exclusively in North America through Red Rock Distribution in partnership with inventor and family-owned manufacturer SEC Manufacturing in Taiwan.
