All-scenario Fastening Solutions
Our machine screws are the core of precise mechanical assembly. They use accurate threads and pre-drilled holes to secure mechanical components, offering high load-bearing capability and resistance to loosening. These screws are suitable for electronic equipment, precision machinery, and hardware assemblies, ensuring reliable connections in industrial manufacturing.
Self-tapping metal screws simplify metal sheet installation. The sharp threads penetrate the metal directly without pre-drilling, speeding up assembly for metal frames, sheet metal panels, and small metal parts. This reduces installation time while ensuring a secure connection.
Plasterboard screws are engineered for gypsum boards in interior decoration and ceiling construction. Their fine threads and anti-slip design securely fix boards to the keels, preventing sagging or cracking—commonly used in home ceilings, commercial spaces, and partition walls.
Chicago screws feature a double-sided detachable design for bags, signage, and decorative connections. They combine neat appearance with easy disassembly, widely applied in furniture accessories, advertising signs, and decorative panels.
Cabinet screws ensure stable furniture assembly for wardrobes, cabinets, and shoe cabinets, with tight threads and strong load capacity, preventing long-term loosening or deformation. They are essential consumables in furniture manufacturing.

Sheet Metal, Masonry & Roofing SolutionsSheet metal screws are designed for thin metals such as steel plates, galvanized sheets, and aluminum alloy panels. The sharp threads provide strong locking without damaging the base material, ideal for ventilation ducts, electrical boxes, and decorative panels.
Masonry screws are hardened for concrete, brick, and stone substrates, offering strong anchoring and anti-pullout force. They are suitable for heavy engineering applications, including exterior walls, equipment mounting, and curtain wall supports.
Roofing screws include waterproof gaskets combined with high-strength threads, ensuring secure attachment of color steel sheets, solar panels, and metal roofing structures, even under harsh weather conditions.
Masonry Screws for Hard Substrates
For concrete, brick walls, and stone, masonry screws are hardened for high strength, providing strong anchoring and excellent anti-pullout performance. They can be directly driven into walls for permanent fixation and are suitable for heavy-duty applications such as exterior wall installation, equipment mounting, and curtain wall supports. These screws are widely recognized as the preferred choice for hard substrate fastening.
Roofing Screws for Waterproofing
In roofing and waterproofing projects, roofing screws are designed with special waterproof gaskets and high-strength threads. They can securely fix color steel sheets, solar panels, and insulation boards, providing dual protection against water leakage. With strong weather resistance and rust prevention, these screws are suitable for diverse roofing scenarios, effectively minimizing water leakage risks.
Decorative & Round-head Screws
For general decoration and small accessory installations, pan-head screws feature an umbrella-shaped round head, offering a large load-bearing area and smooth surface finish. The cross-slot design ensures easy installation without slipping. These screws are versatile for panels, decorative elements, and small mechanical accessories.
Tapcon Concrete Screws for Permanent Anchoring
For permanent concrete anchoring, Tapcon-style screws can be directly screwed into concrete without pre-drilling. They provide stable anchoring and high load capacity, ideal for large equipment installation, steel structures, and pipe supports, meeting the safety requirements of heavy engineering projects
