Self-Drilling Metal Roofing Screws Manufacturers

-- Steady & Reliable Manufacturer --

Introduction

Self-Drilling Metal Roofing Screws are engineered for the rapid and secure attachment of metal roofing and siding panels to purlins or steel frames. The integral sharp drill point and threading mechanism eliminate the need for pre-drilling, drastically speeding up installation. Equipped with a sealing washer (often EPDM bonded), these screws create a watertight seal, protecting the structure from moisture ingress and ensuring the long-term integrity of the roof envelope.

  • Watertight Seal: The EPDM washer compresses to prevent leaks and thermal movement damage.

FAQ

  • Q: How do I select the correct drill point size?
  • A: The drill point number must match the total thickness of the metal being penetrated. A #3 point is typically used for connecting thin metal sheet to steel purlins up to 0.25 inches thick, while a #5 point is needed for thicker structural steel.
  • Q: What is a bi-metal roofing screw?
  • A: A bi-metal screw features a stainless steel head and shaft for corrosion resistance, fusion-welded to a hardened carbon steel drill point. This combines the drilling performance needed for steel with the long-term durability of stainless steel.
