Malco® Zip-In® HW7X1/2ZX Self Piercing Screw, #7, Hex Head, Slotted Drive, Steel, Zinc Plated, Self-Piercing Point
Part #: MALHW7X1/2ZX
MFG #: HW7X1/2ZG
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, 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. Zip-In® screws are faster driving, with a greater capacity for fastening heavier gauges of sheet metal than any other self-piercing type.
