Malco HW8X3/4 ZWG Sheet Metal Screw for Professionals (100 Pack), 3/4 Length, White

Malco's Zip-in® Screws stand out for their exceptional quality and have earned a reputation as one of the top choices for fastening HVAC metal ducts. The distinct thread design coupled with quality-controlled manufacturing sets Zip-in® sheet metal screws apart from the competition.

These screws undergo an advanced heat treatment process, enabling them to taper to a fine, sharp point without compromising point strength—an essential feature for effective penetration. A single, continuous starting thread extends all the way to the tip, which is instrumental in delivering Zip-in®'s remarkable penetrating power. Upon initial penetration, a secondary thread activated above the point further enhances the screw's ability to drill in rapidly, resulting in a swift fastening process.

Compared to other self-piercing screws, Malco's Zip-in® screws are designed for faster driving and have a superior capacity for fastening heavier gauges of sheet metal. This efficiency makes them a favored option for professionals in the HVAC industry.

For optimal results, it's recommended to pair any Zip-in® Sheet Metal Screw with the Malco C-RHEX™ Cleanable, Reversible Dual Sided Hex Driver. This combination ensures that you get the best performance out of your fastening tools, maximizing both speed and precision during installation.

In summary, if you're looking for screws that offer a blend of quality, efficiency, and superior fastening capabilities for HVAC metal ductwork, Malco's Zip-in® Screws are undoubtedly a top contender. Their innovative design, combined with the right driver, will help you tackle even the toughest sheet metal applications with ease.
