Meet the Malco 8X2 White Zip-In Self-Piercing Screws — the bulk solution for fast, dependable metal fastening. This 2300-count box pairs a 1/4″ slotted hex washer head with a durable zinc-plated finish, engineered to deliver precision performance on sheet metal projects from flashing to HVAC ductwork.
What makes Zip-In different
A uniquely engineered thread design and meticulous heat-treat process power the Zip-In advantage. The screw tapers to a fine, sharp point without sacrificing point strength, so entry is clean and predictable every time. A single starting thread extends down to the tip, creating immediate penetration grip, while a second thread above the point engages after initial entry to drive the screw in double fast. This combination results in faster driving and a superior capacity to fasten heavier gauges of sheet metal than typical self-piercing screws.

Practical use cases and best practices
For quick installations on thin to mid-thickness sheet metal, simply align components and drive with a steady, controlled motion. Let the Zip-In point do the work, and avoid over-torquing to preserve thread integrity. When working with thicker metal, the second-thread engagement helps maintain drive speed and reduces the need for pre-drilling, making assemblies faster and more consistent. This screw set is especially valuable on large-scale projects where speed and durability matter—from professional contractors to serious DIY enthusiasts.
