China Screw Manufacturers, Suppliers, Factory

Jinghong Manufacturer specializes in supplying cross-head micro machine screws for watches and precision instruments. Made from 304/316 stainless steel, these screws feature ultra-precision threads ranging from M1.2 to M4, with accurate cross slots, rust resistance, and durability. Designed specifically for the extremely fine assembly of watch cases, straps, movement brackets, and optical equipment.

Jinghong manufacturer provides Stainless Steel Hex Lag Screws, which combine excellent corrosion resistance and strong self tapping performance. No need for pre drilling, the hexagonal head design facilitates wrench operation and provides high torque fastening. Widely used in various industrial scenarios with high anti-corrosion requirements.

The Carbon Steel Adjusting Screw is specifically designed for scenarios that require frequent manual disassembly or are difficult to reach with tools. The high head provides ample force application space, the full circumference rolling pattern ensures strong grip, and the galvanized surface can effectively prevent rust. Widely used for quick fixing of chassis panels, equipment access doors, exhibition equipment, and various industrial enclosures.

Stainless Steel Hexalobular Socket Pan Head Screws (M2-M10) utilize 304 stainless steel and a Torx drive design to deliver high torque transmission and anti-stripping performance. The pan head enables flush installation, while precision cold heading ensures thread accuracy, maintaining excellent corrosion resistance in harsh environments. Ideal for medical devices, precision electronics, and other applications demanding high hygiene standards and assembly reliability.

The ClickBlack Flat Head Gypsum Screw is made of pure hard carbon steel, paired with sharp self tapping drill bits and deep blackening anti rust treatment, achieving fast screwing, strong locking, and long-term anti rust. The black appearance and countersunk design of the screws ensure structural strength while achieving a "hidden" effect at the installation point, improving construction efficiency and final aesthetics.

Copper Plating Welded Studs is a body functional fastener designed specifically for efficient grounding connections, conductive assembly, and welding applications. A high-purity copper layer is uniformly covered on high-strength screws through electroplating process, which combines the mechanical strength of the steel core with the excellent conductivity and weldability of the copper surface.
