Meet Malco 8X1 Zip-In Self-Piercing Screws (HW8X1ZG) — a purpose-built fastener engineered to transform sheet metal installation. With Zip-In’s signature thread design and precision heat-treating, these screws deliver penetrating power and dependable strength in a single, clean motion.
What makes Zip-In different
- Single starting thread is formed all the way to the tip, creating a precise starting point that kickstarts penetration with minimal effort.
- Second thread above the point engages after initial entry, effectively drilling in twice as fast and locking the metal securely as you drive.
- Advanced heat treat process sharpens the point into a fine, piercing tip without sacrificing point strength, so you can trust it to bite through tougher gauges of sheet metal.
- Faster driving, higher capacity than traditional self-piercing screws, making it ideal for thicker metals where reliability matters.
Product specs at a glance
- Size: 8x1 (8 gauge, 1 inch length)
- Drive: slotted with 1/4 inch hex washer head for a secure, flush fit
- Finish: Zinc plated for corrosion resistance
- Quantity: 100 screws per pack
Ideal uses and scenarios
- Secure thicker sheet metal in roofing, flashing, ductwork, and metal enclosures where standard screws struggle to bite.
- HVAC installations that require a rapid, reliable fastener that maintains a tight seal over time.

Why choose Zip-In over conventional self-piercing screws
- Better performance on heavier gauges without pre-drilling—reduces time on the job.
- Sharper point and doubled-thread progression mean cleaner starts and steadier progression through metal.
- Durable zinc finish protects against corrosion in exposed applications, extending the life of your installation.
Practical tips for best results
- Clean the work surface to prevent debris from obstructing the initial thread engagement.
- Apply steady, moderate torque to leverage the two-thread engagement without overdriving.
- Use in combination with compatible washers and mating metals to ensure a solid seal where weatherproofing is a concern.
