The 8.8 grade Hexagon Fit Shank Bolts are a type of high-strength mechanical fastener. They undergo quenching and tempering heat treatment to meet the 8.8 grade strength standard, and their surfaces are usually treated with blackening. The key feature of these screws lies in the presence of a precise threaded section in the middle. During installation, they adopt transitional or interference fits with the threaded holes, enabling precise positioning and gap-free connection of components. Compared to ordinary bolts, their lateral shear resistance is significantly stronger. They mainly rely on their own shear strength rather than pre-tightening friction to bear the shear force. This product is widely used in machine tools, automobiles, molds, and automation equipment, which have high requirements for position accuracy and shear-bearing capacity in critical connection parts.

Disc Shaped Embossed Washing is made of spring steel stamping, with a surface treated with zinc plating or blackening. Equipped with a circle of radial embossed teeth, installed under the nut and pressed, the teeth bite tightly against the contact surface. It is much more anti loosening and anti slip than a smooth washer, suitable for situations with tight space and anti slip requirements.

Jinghong Factory specializes in producing Trox Low Cylindrical Head Screws, which are made of high-quality carbon steel and have a short cylindrical head. Trox groove with blue and white zinc treatment on the surface, suitable for assembly occasions with limited headroom. The Trox groove drive is not easy to slip and is suitable for quick locking of pneumatic or electric tools.

Jinghong Factory specializes in producing Double Layered Self locking Anti Loose Washing, which is made of 304 stainless steel and consists of two pairs of washers with wedge-shaped teeth. The product is locked using the wedging principle and can maintain locking force under severe vibration and temperature changes. It is commonly used in situations with high anti loosening requirements.

Stainless Steel Trox Flat Head Machine Screw, 304 material, countersunk head, hexagonal drive. The head remains flush with the surface after tightening, ensuring no sharp edges. The hexagonal drive offers better torque transmission than a cross-head, reducing the likelihood of slipping and ensuring efficient torque transfer.

Jinghong Factory specializes in producing Nylon Grub Hex Screw, which is made of high-quality nylon injection molded or machined. The head is an inner hexagon and the tail is flat. Nylon material is non-conductive and non-magnetic, and does not damage the workpiece. After tightening, nylon locks the position by friction, playing a role in preventing loosening. The length can be customized according to demand, and regular sizes are readily available in stock.
