Self-drilling, stainless steel fastener for steel and timber substrates.

For use where the internal relative humidity is in excess of 65% or for chemically aggressive atmospheres or conditions, for example: coastal environments.

Ideal for use in refurbishment applications where the detailed condition of the existing roof is not known or when the build up contains abrasive layers that may damage the corrosion protection of carbon steel fasteners and make them ineffective.

For applications where an extended design life and warranty is required.
