Hex Flange Coarse Thread Drill Screw (Self-Drilling)
Key Features:
Material: High-grade 1022A carbon steel for robust strength, durability, and fatigue resistance.
Dimensions:
Diameter Range: 5.5mm to 24mm (coarse thread design for rapid installation).
Length Options: 25mm, 32mm, 38mm, 45mm, 50mm, 65mm, 75mm, 100mm, 125mm, 150mm, 165mm, 175mm, 200mm, 300mm (customizable for diverse applications).
Coating: Superior corrosion-resistant coating with salt spray resistance ratings of 500H, 1000H, or 1500H, compliant with Class 3/Class 4 standards for long-term performance in harsh or humid environments.
Hardness:
Core Hardness: 380–440 HV (engineered for flexibility and shock absorption).
Surface Hardness: 620–720 HV (precision heat-treated to maximize wear resistance and drilling efficiency).
Design:
Hex Flange Head: Ensures secure grip with standard hex tools and distributes load evenly to prevent surface damage.
Coarse Thread: Enhances grip and speed in soft or composite materials (e.g., wood, plastic, light-gauge metal).
Self-Drilling Tip: Eliminates pre-drilling, reducing installation time and labor costs.
