Malco® HW8X1/2Z MALHW8X1/2Z

Malco® Zip-in® screws are known for their superior quality and is considered by many for being the best screw choice for HVAC metal duct fastening. A unique thread design and quality controlled manufacture spell the Zip-in® sheet metal screw difference. Zip-in® are made with a sophisticated heat treat process which allows the screw to taper to a fine, sharp point without sacrificing critical point strength. A single starting thread is formed down to the very tip of the point and is the source of Zip-in® penetrating power. A second thread above the point engages after initial penetration and drills in the screw double fast. Malco® Zip-in® screws are faster driving, with a greater capacity for fastening heavier gauges of sheet metal than any other self-piercing type. For the best performance, use any Zip-in® sheet metal screw with a Malco® C-RHEX™ cleanable, reversible dual-sided hex driver.
