M2M5M6 Carbon Steel Black Zinc Plated Thin Flat Head Hexagon Screws Large Flat Head Hexagon Screws Flat Head Bolts for Construction & Home Renovation

Our Black Zinc Plated Carbon Steel Thin & Large Flat Head Hexagon Screws—also known as flat head bolts—are high-strength fastening solutions available in M2, M5, and M6 sizes, engineered for versatility across furniture hardware, DIY projects, metal fabrication, construction, and home renovation. Crafted from premium carbon steel with a black zinc plated finish, these hexagon screws combine exceptional durability, corrosion resistance, and a sleek, low-profile design, making them ideal for both professional installations and DIY enthusiasts.

 

The carbon steel core delivers robust strength and load-bearing capacity, ensuring reliable performance for light-to-heavy-duty fastening tasks—from securing furniture hardware (cabinetry, shelves, brackets) to assembling metal components and construction trim. The black zinc plating enhances corrosion and rust resistance, protecting the screws from moisture, wear, and environmental damage, while also providing a sleek, professional black finish that complements various hardware and decor styles.

 

Designed with both thin and large flat head options, these hexagon screws offer versatile installation flexibility. The flat head design sits flush with the surface, eliminating protrusions and creating a clean, streamlined look—perfect for furniture, visible hardware, and decorative installations where aesthetics matter. The hexagon (hex) head allows for easy torque application with standard hex tools, reducing slippage and ensuring secure, efficient installation every time.

 

Available in M2, M5, and M6 sizes, these screws cater to a wide range of applications: furniture hardware installation (drawers, cabinets, tables), DIY home projects (shelving, wall mounts), metal fabrication (sheet metal, frames, brackets), construction (trim, light fixtures, small structural components), and equipment assembly. Their precision-machined threads ensure a tight, anti-loosening hold in wood, metal, plastic, and composite materials, maintaining stability even in high-vibration environments.

 

Precision-manufactured to meet strict industrial standards, each screw undergoes rigorous quality control to ensure consistent sizing, thread accuracy, and durability. Whether you’re a professional contractor, furniture maker, or DIY hobbyist, our Black Zinc Plated Carbon Steel Thin & Large Flat Head Hexagon Screws (M2/M5/M6) deliver the strength, versatility, and corrosion resistance needed for long-lasting, professional-grade fastening.
