M2/M3/M5 8.8 Full-tooth nickel-plated cup head inner hexagonal self-tapping screws cylindrical head furniture self-tapping screws for Furniture Assembly

Our 8.8 Grade Full-Tooth Nickel-Plated Hex Socket Self-Tapping Screws (Cup Head/Cylindrical Head) are professional-grade fasteners engineered for reliable, long-lasting fastening in furniture assembly, woodworking, and DIY repair projects. Crafted with 8.8 grade high-strength steel and a nickel-plated finish, these screws offer exceptional durability, corrosion resistance, and anti-rust performance—ensuring they hold securely even in humid environments or with frequent use.

 

The full-tooth design enhances grip and load-bearing capacity, while the hex socket (inner hexagonal) drive provides precise control during installation, preventing slipping and reducing damage to the screw head. Available in two practical head styles—cup head and cylindrical head—they cater to different furniture assembly needs: the cup head offers a sleek, low-profile finish for a neat appearance, while the cylindrical head provides extra stability for heavier furniture components.

 

Designed as self-tapping screws, they eliminate the need for pre-drilling in most soft materials (wood, MDF, particleboard), saving time and effort for both professionals and DIY enthusiasts. Available in common sizes M2, M3, and M5, these screws are perfectly suited for furniture assembly (chairs, tables, cabinets), woodworking projects, furniture repair, and light-duty hardware installation.

 

Nickel-plated surface not only enhances corrosion resistance but also adds a smooth, professional look, making them ideal for visible furniture surfaces. Suitable for furniture manufacturers, carpenters, DIY hobbyists, and hardware suppliers, these screws are also available for wholesale bulk orders—combining professional strength, easy installation, and versatile functionality to meet all furniture fastening needs.
