Jinghong manufacturer specializes in producing DIN439 hexagonal thin nuts, with specifications ranging from M2 to M64, produced according to the German standard DIN439, divided into two series: fine tooth and coarse tooth. The product is made of high-quality carbon steel cold heading forming, and the surface can be galvanized, blackened or treated with natural color. The thickness is only about half of the standard nut, suitable for situations with limited space or requiring anti loosening fit.

Jinghong Factory specializes in producing ISO 10642 Hexagon Socket Head Screws, which are made of high-quality carbon steel and designed with hexagonal. After installation, the screw head can be embedded to achieve a flat and non protruding invisible connection. We offer various strength grades such as 8.8, 10.9, 12.9, etc. The surface can be galvanized, blackened, or treated with natural color. After installation, it can be flush with the workpiece surface, which is both beautiful and can avoid interference, suitable for various fields.

ISO7042 All-metal threaded locking thick nuts (M5-M36) adopt the threaded compression deformation technology to achieve non-nylon elastic locking. They have a wide temperature tolerance range, and the thickened design enhances the anti-detachment strength. The surface blue-white zinc coating provides long-term corrosion resistance. They are suitable for reliable anti-loosening connections in high-vibration, high-temperature and heavy-load scenarios such as heavy machinery, automobiles, and steel structures.

Jinghong Manufacturer specializes in providing ISO 7091 Flat Washers, which are made from high-quality carbon steel and stainless steel, with a product grade of Class C. These washers are suitable for use with bolts and nuts to distribute pressure, protect workpiece surfaces, and prevent loosening. They are widely used in various maintenance fields such as building structures.

The Lock Washers for 65Mn GOST 11872 round nuts is a multi-tongue locking gasket made of 65Mn spring steel. It is specifically designed for the anti-loosening locking of GOST 11871 round nuts. The core part is used for axial positioning anti-loosening in high-vibration and high-load working conditions. It is a key fastener for mechanical transmission and equipment locking.

Jinghong Factory specializes in producing Carbon Steel ISO 7090 Flat Washers, with specifications covering the M1.6-M64 standard series. It is made of high-quality carbon structural steel cold-rolled and can be treated with galvanizing, blackening, and other treatments on the surface. The product complies with ISO7090 standard, with an enlarged outer diameter and chamfered design, suitable for high-strength bolt connections, effectively dispersing pressure and protecting the surface of the workpiece. Regular specifications available in stock, supporting non-standard customization.
