Product Description

Malco 8X1 Zip-in Self-Piercing Screws | 1/4" Slotted Hex Washer Head Sheet Metal Screws | Fast & Easy Piercing | Zinc Plated (500 Count)

Undercut-indented hex washer slotted head always seats flush.
Full 1/4 in. (No. 8) head will not strip out of hex driver opening at any-time during operation.
Complete operator control with precise hole alignment.
Combination lead double thread Instantly penetrates and engages in heavy gauge sheet metal and layered light gauge.
Starting thread machined down to very tip of screw point.

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.
