Composite drill-point screws are specially designed fasteners whose heads and tails are typically crafted from different materials or alloys to meet specific performance requirements. Deepfastener composite drill-point screws feature 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 additional strength, corrosion resistance, and other advantageous properties.
