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.

Our factory specializes in producing high-strength cross countersunk head drywall screws. Made from high-quality carbon steel, they undergo carburizing heat treatment, achieving a surface hardness of 45-53HRC. The threads are coarse thread self-tapping type, with a pointed tail, and are designed with a cross recessed countersunk head, making them widely used in installation and other scenarios. The main specifications are M3.5, with lengths ranging from 16mm to 70mm, and we have ample stock of conventional sizes.

Our factory specializes in producing carbon steel galvanized Torx Countersunk MDF screws, using high-quality carbon steel with countersunk heads and Torx grooves. The surface is treated with blue white zinc or color zinc plating. After installation, the countersunk head is flush with the surface of the workpiece, and the plum blossom groove drive does not slip. It is suitable for connecting wooden boards such as fiberboard, density board, and particleboard. Widely used in various construction industries.

Our factory specializes in producing Spiral Wire Nuts, which are made of nylon PA66 or flame-retardant PP for the outer shell and equipped with high elasticity carbon steel springs inside. The product is connected to wires through a rotating locking method, without the need for welding or tape wrapping, with firm wiring and low contact resistance. Widely used in internal wiring scenarios.
