Malco HW7X1/2ZWG Zip-In Self Piercing Sheet Metal Screws, White, 100 Count

A unique thread design and quality controlled manufacture spell the Zip-In sheet metal screw difference. Zip-In’s 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’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.
