Bilot HW8X3/4ZT #8x3/4 Zip-in Self Piercing Screw 1000-Pack, Multi, 1000

A unique thread design and quality controlled manufacture spell the Zip-In difference. Zip-In's sophisticated heat treat process allows the screw to taper to a fine, 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. Zip-In screws are faster driving, with a greater capacity for fastening heavier gauges of sheet metal than any other self-piercing type.A unique thread design and quality controlled manufacture spell the Zip-In difference.
