Zip-In® Self Piercing Sheet Metal Screws


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.

For the best performance, use any Zip-In® Sheet Metal Screw with a malco MSHC Cleanable, Reversible Dual Sided Hex Chuck Driver.


Rated #1, Zip-in® Screws are the Best Selling Sheet Metal Screw Worldwide.

The very best screws in the industry
I have been in the industry for over 30 years, as far as I know I have used zip in screws from Malco every since I started in the trade. In the past 23 years I have owned my own business, I have tried other screws and always come back to Malco. Visit me http://alpineheat.com/
