For roofing systems that require maximum embedment into steel framing, this ST Fastening #12 x 3" ZXL Steelbinder screw delivers extended reach and dependable holding strength. The electro-galvanized finish enhances corrosion resistance for exterior applications, making it suitable for commercial, industrial, and agricultural projects. Each 250-count box keeps large-scale installs moving efficiently.

Note: Confirm panel assembly thickness and steel gauge compatibility before installation.

Electro-Galvanized 3" ZXL Self-Drilling Roofing Screw for Steel Structures

Engineered for exposed fastener metal roofing systems, this longer self-drilling fastener provides deep steel penetration and consistent compression at the panel surface.

Key Features

  • Extended 3" Length: Designed for thicker roof assemblies requiring deeper embedment.
  • Electro-Galvanized Coating: Supports corrosion resistance in exterior environments.
  • Self-Drilling Tip: Eliminates pre-drilling when fastening into steel.
  • ZXL Steelbinder Construction: Built for reliable steel-to-steel panel attachment.

Common Applications

  • Commercial Metal Roofing: Secures panels to structural steel framing.
  • Industrial Buildings: Suitable for warehouses and manufacturing facilities.
  • Agricultural Structures: Attaches roofing on barns and equipment storage buildings.
  • Insulated Panel Systems: Used where additional fastener length is required.
  • Roof Retrofits: Replacement fasteners for steel-framed roof systems.

Installation Tips

  • Drive at Controlled Speed: Allow the drill point to fully penetrate steel.
  • Maintain Perpendicular Alignment: Ensures proper washer seating and compression.
  • Seat Securely: Tighten until the washer is evenly compressed without over-tightening.

Great Metal Roofing Screws

I paid a little extra for the ZXL Steelbinder Metal Roofing Screws. They worked great for drilling into the heavy gauge steel purlin. No pre-drilling necessary. Looks like they will hold up for many years to come.
