Innovation comes to fastening ductwork: S-MS HVAC Zip Screws
For years, conventional screws utilized for HVAC duct fabrication and installation have gone unchanged. Having to choose between sharp and self-drilling screws to cover their application range, installers were forced to choose between imperfect solutions: Sharps are preferred for their off-angle fastening but are limited to light gauge metal; self-drillers easily handle heavy-gauge materials but are prone to “walking” if not held perpendicular. Now, Hilti has blended the best of both fasteners with the new S-MS HVAC Zip Screws. The new Hilti screws utilize HyperThread technology to deliver off-angle fastening, even in heavy-gauge sheet metal.
