AS3566.2 Self Tapping Drilling Screws With EPDM GRY Washer
Hex Washer Head | Anti-Corrosion Coating | Gray EPDM
Why Choose AS3566.2 Self Drilling Screws?
Leak-Proof Seal
Integrated EPDM gray washer expands & seals against metal sheets, preventing water ingress. Perfect for roofing and exterior applications.
Self-Drilling Point
No pre-drilling needed. Drills, taps, and fastens in one operation, cutting labor time by 50% on metal substructures up to 2.5mm thickness.
Corrosion Resistant
Advanced coating (Geomet/Zinc flake) + baked topcoat provides 1000+ hrs salt spray resistance. Ideal for coastal & industrial zones.
AS3566.2 Certified
Complies with Australian standard for self-drilling screws. High tensile strength, superior pull-out values, and ductility.

Engineered for Excellence – Why Choose EPDM Gray Washer?
The EPDM (Ethylene Propylene Diene Monomer) gray washer offers excellent resistance to weathering, ozone, UV radiation, and temperature extremes. Combined with our self tapping drilling screws, it eliminates water leakage around fastener holes while maintaining consistent clamping force. Perfect for metal roofing fasteners in residential, commercial & agricultural projects.
Additionally, the unique design of AS3566.2 self drilling screws ensures reduced risk of corrosion creep and provides longer service life compared to standard screws. The hex head allows for high torque installation without stripping.
Fast Installation
Self-drilling point eliminates pre-drilling, saves up to 60% installation time on metal substructures.
Weatherproof EPDM
Gray EPDM washer seals perfectly, high UV resistance and remains flexible from -40°C to 120°C.
High Pull-Out Strength
Engineered thread profile ensures maximum holding power in steel and light gauge metal.
