Product Description
A unique thread design and quality controlled manufacture spell the zip-In difference. The zip-In's sophisticated heat treat process allows the screw to taper to a fine, sharp point without sacrificing it's 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 then drills in the screw double fast. The zip-In screws are faster driving, with a greater capacity for fastening heavier gauges of sheet metal than any other self-piercing type.
