Grade 8.8 hexagonal bolts are made of high-quality carbon steel and undergo heat treatment to achieve a tensile strength of 800MPa and a yield strength of 640MPa, meeting the requirements of medium and high load scenarios. The nuts and washers are made of the same material or high elastic alloy steel to ensure long-lasting and stable locking force. The product is provided as a three piece set of "bolt+nut+flat washer" for driving.
The hexagonal head design of the bolt is compatible with universal tools, improving construction efficiency. The flat washer can disperse pressure and prevent loosening. The presence of the nut can maintain pre tension even in vibration environments.
Jinghong manufacturer uses a multi station high-speed cold heading machine for one-time molding, with high thread accuracy, reducing assembly friction, and improving connection efficiency. Adopting vacuum quenching and tempering processes to eliminate internal stress and ensure stable performance of bolts. Jinghong suppliers use high-strength alloy steel to manufacture products and perform surface treatment on some products. Surface treatment methods include galvanizing, spraying, chrome plating, etc. Among them, environmentally friendly electroplating treatments such as environmentally friendly blue zinc, environmentally friendly color zinc, environmentally friendly nickel, environmentally friendly white zinc, etc. are widely favored by the market. The environmental protection concept is in line with the current international concept of harmonious coexistence between humans and nature.
