SELF-DRILLING SCREWS

AMSI self-drilling screws are an excellent choice for all metal roofing and standing seam metal roofing fastening requirements.

These screws are designed for superior performance in metal-to-metal applications, ensuring strong, reliable connections for metal roof clips and other essential components.

All AMSI self-drilling screws feature a panhead design, with either phillips or combo drive. Head thickness is 0.084"+/-.

  • ASO-3 is #2 Phillips drive
  • ASO-4 is combo drive
  • SSF-101-SD is combo drive
  • Meets or exceeds ASTM C-1513 and/ or ASTM C-954
  • Galvanized or 410 stainless steel

ULTIMATE VALUE CHARTS:

Our self-drilling screws have been rigorously tested for performance in metal roofing and standing seam metal roofing applications. Below are the results based on standardized ASTM testing protocols:

Steel: Screws were driven into steel, ensuring three (3) exposed threads on the off-side of the connection before being tested for pull-out strength.

Wood: Screws were driven 3/4" into wood material, then subjected to pull-out tests using a testing machine.

Note that all results were obtained in strict adherence to ASTM test protocols. These ultimate figures are offered only as a guide and are not guaranteed in any way by AMSI (Architectural Metal Specialties Inc.). A 4:1 safety ratio is recommended.

INSTALLATION GUIDELINES:

Proper installation is critical for ensuring the performance and longevity of your self-drilling screws in metal roofing projects. Follow these guidelines for best results:

  • Use a 0-2500 RPM screw gun with torque adjustment to prevent overdriving. Overdriving may cause fastener failure or strip-out of the work surface.
  • Ensure the fastener is fully seated, with the screw head's bearing surface flush against the work surface.
  • When securing metal roof clips, confirm that the fasteners penetrate the framing securely for maximum holding power.
  • Always wear eye protection when driving screws, as screws and driver bits may fracture or shatter, posing a risk of serious injury or blindness.
