Frequently Asked Questions

The SDZ1220 screw is designed primarily for metal-to-metal fastening applications. It is commonly used in steel framing, metal roofing, HVAC systems, and commercial construction projects.

The #3 self-drilling point allows the screw to drill and fasten in a single operation. This eliminates pilot holes and improves installation efficiency.

The hex washer head provides excellent driving stability and distributes clamping force evenly. It also helps reduce cam-out during installation.

The zinc-plated finish provides basic corrosion protection and performs well in many indoor and light exterior environments. For highly corrosive conditions, a premium coated fastener may be recommended.

A drill or screw gun equipped with a 5/16-inch hex driver is recommended. Following the recommended RPM helps achieve optimal drilling and fastening performance.
