Composite self-drilling screws are specially designed fasteners featuring heads and tails typically crafted from distinct materials or alloys to fulfil specific performance requirements. Deepfastener composite self-drilling screws employ a dual-metal construction combining stainless steel and alloy steel. This design enables the screws to self-drill into target materials during installation while delivering enhanced strength, corrosion resistance, and other properties.
