Note: The above steel fixing fastener sizes are suitable for fixing over an insulation blanket up to 55mm thick. For thicknesses up to 100mm, the next standard screw length to that indicated is to be used. For timber fasteners, the next standard screw length to that indicated may be required with minimum 25mm timber embedment to be maintained.

Classes: Protective coatings applied to fasteners provide various levels of protection. The Australian Standard for fastener performance (AS3566) currently lists three classes of corrosion coatings with a proposed fourth.

** Class 3: For general external use in mild and moderate industrial and mild marine applications. Stratco strongly recommends that Class 4 fasteners be used in moderate marine applications. Class 3 is intended for roofing and cladding fasteners in standard applications.

^ Class 4: For external use in moderate and severe marine environments, classified in accordance with ISO 9223 as generally between 100m from the beach front to approximately 300m inland. In high winds this may extend further inland. Fasteners conforming to Class 4 should be used with Ultra steel and XRW steel (when used 200-400m from marine environments).

Screw Fastener Code

The number code format is:

Typical Hex Head

Top threaded section
Extrudes sheeting towards the seal to maximise waterproofness. Grips the sheeting for a secure connection. Stops sheeting from moving when walked on.

Dwell section
Prevents the sheeting from riding up during fixing and minimises distortion of the profile.

Shank hole enlarger
Enlarges the hole in the sheeting to minimise damage to the protective coating on the screw.
