High-Quality Black Self-Drilling Metal Screws for Efficient and Lasting Installations

The construction hardware sector has witnessed 18% annual growth since 2020, driven by advanced solutions like high-quality black self-drilling metal screws. These corrosion-resistant fasteners combine zinc-nickel plating with proprietary drill point designs, achieving 35% faster penetration rates compared to standard Phillips-head screws.

Material Science Behind Modern Fasteners

Our M4 stainless steel washers utilize cold-forged 316 stainless alloy, demonstrating 82kN tensile strength in ASTM F606 testing. The surface-treated black screws feature:

• Triple-layer epoxy coating (38-42μm thickness)
• 120° drill points with anti-skip grooves
• Torque resistance up to 9.2Nm (±0.3Nm)
