Our factory specializes in producing Flat Head Half Hex Rivet Nuts. The head of the product is flat, and the body is semi-hexagonal. It is made of high-quality carbon steel and surface-treated with blue-white zinc plating. All operations are performed on the front side of the plate, and the riveting is completed with a single pull of the riveting gun. It can be directly installed on assembled boxes, sealed pipes, and workpieces that are inconvenient to turn over. There is no need to go to the back to hold the nut or weld.

Our factory specializes in producing Dacromet Coach Bolts, crafted from high-quality carbon steel. The bolt head is shaped as a semi-spherical dome, while the neck is square, with a Dacromet coating on the surface. When installed, the square neck clicks into the square hole of the workpiece, preventing the bolt from rotating with the nut, allowing for easy tightening by a single person. The Dacromet coating exhibits excellent salt spray resistance and is suitable for various applications. The bolt is available in strength grades of 4.8, 8.8, and 10.9, with standard sizes in stock and support for non-standard customization.

Our factory specializes in producing 304/316 stainless steel turnbuckles (also known as turnbuckle screws, turnbuckle turners, and turnbuckle clamps), which are precisely processed and formed using high-quality stainless steel bars or plates. The product achieves precise tensioning of steel wire ropes, cables, or tension rods by rotating the middle sleeve to simultaneously adjust the extension length of the screws at both ends. The end forms include loop type (OO), loop hook type (OC), etc., which are widely used in various industries.

JINGHONG factory specializes in producing striking plastic expansion tubes with screws, made of high-quality polyethylene (PE) or nylon, and equipped with carbon steel galvanized self-tapping screws. The outer wall of the expansion tube features barbs and guide grooves, allowing it to be directly hammered into the wall without the need for an electric drill to expand the hole. It is widely used in various applications. The specifications range from 6mm to 10mm, and we have ample stock of regular sizes.

Black zinc cap nuts, manufactured to GB/T 923 or DIN 1587, feature a closed domed top that fully covers exposed bolt ends for safety and a clean appearance. Made from cold-headed carbon steel with a matte black zinc finish, they offer enhanced corrosion resistance over standard finishes. Internal threads are precision-machined to 6H tolerance across M3 to M20 sizes, ensuring reliable engagement. The standard hex base accepts common tools for easy installation. Ideal for exposed connections on machinery, furniture, railings, and electrical enclosures where appearance, safety, and protection from dust and moisture are required.
