Malco Zip-in® screws feature a unique thread design and quality-controlled manufacturing process. A sophisticated heat treatment allows the screw to taper to a fine, sharp point without losing critical strength. The single starting thread provides penetrating power, while a second thread engages after initial penetration to drive the screw quickly.This #8 x 2" screw has a white-painted, 1/4" slotted hex washer head and is designed for faster driving and fastening heavier gauges of sheet metal compared to other self-piercing types. They are commonly used for HVAC metal duct fastening and securing registers to walls.
