Our factory specializes in producing Dacromet Hex Flange Bolt, which is made of high-quality carbon steel with a hexagonal flange surface on the head and a Dacromet treatment on the surface. Replacing flat gaskets with flange faces increases the contact area, disperses pressure, and eliminates the need for a separate gasket insertion process. Dacromet coating has excellent salt spray resistance and is suitable for occasions with high requirements for rust prevention. Specifications and lengths can be customized according to needs, and strength grades of 4.8, 8.8, and 10.9 can be produced.

Our factory specializes in producing Black O Seal Rings, which are made of silicone raw materials and do not contain heavy metals or harmful substances. Black appearance, smooth surface, customizable size according to needs. Widely used in occasions with high environmental requirements. Regular size stock is sufficient, supporting non-standard mold customization.

Our factory specializes in the production of pressed rivet nuts, using high-quality carbon steel (with galvanized surface) or 304 stainless steel. These products are installed on workpieces such as thin plates, aluminum plates, and copper plates to form reliable internal threads for subsequent screw connections. After pressing and riveting, the nuts are flush with the workpiece, with a smooth and flat backside, making them suitable for various industries. Specifications range from M2 to M12, with ample stock of standard sizes available.

Our factory specializes in producing DIN928 square welded nuts according to German standards. It is square in shape, with a raised platform and welding points at the bottom, and is used in conjunction with a spot welding machine. After welding, it is firm and not loose. The material can be selected from carbon steel or stainless steel 304, and the surface can be treated. Specifications range from M4 to M16, both coarse and fine teeth can be produced, and regular sizes are readily available in stock.

Our factory specializes in producing carbon steel galvanized A-grade chamfered flat washers. The outer edge of the product is chamfered, with high precision in inner and outer diameter dimensions, and the surface is coated with blue and white zinc. Suitable for use with grade 8.8 and below hex head bolts, screws, and nuts. The specifications range from M3 to M36, with sufficient stock of regular sizes and support for non-standard customization.

The JINGHONG Thin Head Semi-Tubular Rivets are made of high-quality carbon steel and are electroplated with environmentally friendly blue-white zinc on the surface, featuring both aesthetic appeal and basic rust prevention capabilities. Their thin head and large supporting surface design effectively disperse compressive stress, preventing damage to the surface of thin plates or soft materials, and reducing the assembly height to save space. The semi-hollow structure reduces its own weight, requiring less force during installation, and can be quickly completed with manual or pneumatic tools, significantly improving assembly efficiency. The product has high dimensional accuracy and reliable connection, and is widely applicable in light-load permanent fastening scenarios such as automotive interiors, hardware boxes and bags, electronic enclosures, and light industrial products.
