Sheet Metal Screws (Zip Screws)
A unique thread design and quality controlled manufacture spell the Zip difference. Zip’s sophisticated heat treat process allows the screw to taper to a fine, sharp point without sacrificing critical point strength. A single starting thread (A) is machined down to the very tip of the point and is the source of Zip’s penetrating power. A second thread (B) above the point engages after initial penetration and moves the screw in double fast. Zip screws are faster driving, with a greater capacity for fastening heavier gauges of sheet metal than any other selfdrilling type.
Requires only a standard screw gun power tool rated at 2500 RPM equipped with drilling depth locator.
Quantity 1000-5000 and available in larger quantities.
