Nonferrous Metals ISO 8765-2022 Hexagon head bolts with fine pitch thread

Hexagon head bolts with fine pitch thread are high-precision, highly reliable, and widely applicable fastener products. The bolt thread specifications range from M8 to M64, with a pitch varying from 1mm to 4mm. The material is nonferrous metals, for example, copper bolts can be used for occasions with high corrosion protection and electrical conductivity requirements, and aluminum bolts can be used for lightweight materials and high temperature environments.
 
Product Characteristics

• Thread design: The fine thread design makes the bolt have higher self-locking performance and anti-vibration anti-loosening ability, which is suitable for occasions with high fastening requirements, such as thin-wall parts or parts with high anti-vibration requirements. However, due to the shallow depth of the teeth of the fine thread, its ability to withstand tension may be slightly less than that of the coarse thread.
• Coating protection: The bolt surface can be treated with different coatings according to needs, such as blackening, galvanizing, etc., to improve its corrosion resistance and aesthetics. These coatings can also increase the friction between the bolt and the nut to a certain extent, improving the tightness of the connection.
• Hexagonal head: The head of the bolt is designed as a hexagonal shape, which is easy to tighten and disassemble with tools such as wrenches, and improves work efficiency.

Application
        Because of its excellent performance and wide applicability, fine tooth hexagon head bolts are widely used in aerospace, automobile manufacturing, machinery manufacturing, precision instruments and other fields. In these areas, they play an important fastening and connecting role to ensure the normal operation and safety of equipment.
