Malco Zip-In Screws #8 x 1″ Hex Washer Head Sheet Metal 3500 Bucket HW8X1ZP

Malco Zip-In® #8 x 1″ Sheet Metal Screws – 3500 Count Contractor Bucket (HW8X1ZP)

The Malco Zip-In® #8 x 1″ screws are professional-grade sheet metal fasteners designed for HVAC installers and contractors who need speed, strength, and reliability for high-volume ductwork installation.

This listing is for a 3500-count bucket, ideal for commercial HVAC jobs, shop fabrication, and large duct installs where contractors don’t want to constantly restock smaller boxes.

Zip-In® screws feature Malco’s unique thread design and a controlled heat-treat process that allows the screw to taper to a fine, sharp point without sacrificing point strength. They drive faster and offer greater fastening capacity in heavier gauge sheet metal compared to standard self-drilling tips.

✔ Hex washer head with 1/4″ drive
✔ Zinc plated steel construction
✔ Zip-In® high-performance thread
