Malco HW8X11/2Z Zip-In Self Piercing Screws 8x1-1/2 4500ct
Malco's Zip-in Screws are known for their superior quality and are considered by many to be the best screw choice for HVAC metal duct fastening.
Unique thread design and quality-controlled manufacture create the Zip-in sheet metal screw difference. Zip-in's are made with a sophisticated heat treat process that 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's penetrating power. A second thread above the point engages after initial penetration and drills in the screw double fast.
Malco's Zip-in screws are faster driving, with a greater capacity for fastening heavier gauges of sheet metal than any other self-piercing type.
THIS ORDER IS FOR 4500 PIECES.
For Zip-in sizes not included with this order see "Related Products" below or use "Search."
