ST Fastening #12 x 5" InsulDrill Metal Roofing Screw - Bright White, Pkg 100

When insulated roof panels call for a longer fastener, this ST Fastening #12 x 5" InsulDrill screw delivers the reach and holding strength needed for secure attachment into wood substrates. The Bright White head finish keeps your roof lines looking sharp and consistent, especially on white metal roofing and siding. Each 100-count box supports steady progress on larger installs.

Note: Fastener length should be selected to meet your panel and insulation thickness while maintaining proper wood embedment.

5" Bright White InsulDrill Screw with Bonded Sealing Washer

Built for metal roofing and siding systems, this screw combines a self-drilling point for efficient installation with a bonded sealing washer designed to help reduce leaks at the fastening point.

Key Features

  • Extra-Long 5" Length: Ideal for insulated assemblies that require deeper penetration into wood framing.
  • Bright White Finish: Matches white panels for a clean, uniform appearance.
  • Self-Drilling Point: Speeds up installation by eliminating separate pilot-hole steps.
  • Sealing Washer Included: Bonded washer helps create a moisture-resistant seal.

Common Applications

  • Insulated Roof Panel Attachment: Secures steel panels and insulation to wood purlins.
  • Residential Metal Roofing: Suitable for homes, garages, and shop buildings.
  • Post-Frame Construction: Commonly used on pole barns and agricultural structures.
  • Metal Siding Installations: Fastens panels to wood framing on exterior walls.
  • White Roof Systems: Coordinates with bright white panel finishes.

Installation Tips

  • Drive Straight and True: Keep the screw perpendicular for even washer compression.
  • Use Controlled RPM: Moderate speed helps the drill point cut cleanly and protects the washer.
  • Stop at Proper Seat: Tighten until the washer seals, then stop before overdriving.

The Customer Service Rep was great. He had all the information off the top of his head. one of my questions was (With the materials shortage (Screws) would they be able to fill the order? The CS Rep assured me that the company has tons of screws in stock and would easily fill this order. The leed time on the website was 7-10 days. I believe it was exactly the ten days. the screws arrived in a timely manner.
Thank you for the assistance and the screws.
