China Screw Manufacturers, Suppliers, Factory

Our factory specializes in producing hot-dip galvanized external hexagonal bolts, hexagonal nuts, spring washers, and flat washers. We use high-quality carbon steel cold forging to form the complete set, which includes one external hexagonal bolt, one hexagonal nut, one spring washer, and one flat washer. The surface is all hot-dip galvanized. The bolt strength grade is 8.8, and the nut strength grade is 8. They are used in conjunction and have reliable locking.

The Flush-Head Self-Clinching Studs produced by JINGHONG are made by a single-process processing of SUS304 stainless steel. Their surfaces have undergone passivation treatment, featuring naturally excellent anti-rust and corrosion resistance properties. Their flat-head structure, combined with the full circumferential tooth pattern embossing design at the bottom of the head, enables them to form a firm mechanical interlock and interlocking fit with the sheet after being pressed into the thin sheet. They have strong resistance to being pushed out and rotation, and after installation, the head is basically flush with the surface of the sheet, with no protrusions on the back. This product does not require welding or electroplating. The cold pressing process is efficient and environmentally friendly, and is widely applicable in scenarios where thin sheet metal connections for electronic enclosures, automotive interiors, outdoor distribution cabinets, and medical equipment require high standards of anti-corrosion, flatness of appearance, and cleanliness.

This fastener is made of high-quality carbon steel and is formed as a single piece. Its surface is electroplated with blue and white zinc for rust prevention. The head is a standard cross-head, and the screw is equipped with a unique triangular self-locking tooth pattern. The triangular teeth have an extrusion tapping function, so no pre-prepared threaded holes are required during assembly. It can directly tap into base materials such as plastic and thin steel plates, and after locking, it has a self-locking anti-loosening effect. The coating is uniform and shiny, balancing both rust prevention ability and neat appearance. It is a high-efficiency fastener suitable for use in household appliances, sheet metal, and plastic parts.

Our factory specializes in the production of 304 stainless steel chamfered hexagon head set screws, made from 304 stainless steel, with male and female screws used in pairs. The male screw features a chamfered head and hexagon head, while the bolt passes through the workpiece and connects to the female screw.

Our factory specializes in producing carbon steel galvanized Hex Socket Furniture Connectors, using high-quality carbon steel with a hexagonal countersunk head and coarse self tapping threads. After the installation of the countersunk head, it is flush with the surface of the workpiece. The hexagonal drive can be applied with a large torque using a hexagonal wrench. Widely used in wooden structure connection occasions. Standing stock, supporting non-standard customization.

Our factory specializes in producing 304 stainless steel cross disc head triangular screw, using 304 stainless steel, disc head cross groove type, and thread with triangular self tapping locking tooth shape. The triangular thread generates a locking torque through tooth deformation when screwed in, and has anti loosening self-locking function. Specifications range from M2 to M6, with a length of 4-30mm in stock and support for non-standard customization.
