M18*1.5 Blacking Fine Thread Hex Nuts With 13mm Thickness

Product description:

Fasteners are characterized by a wide variety of specifications, different performance and use, and a high degree of standardization, serialization and generalization. Fasteners are the most widely used mechanical base parts, and the demand is very large.

The pitch of this product is 1.5mm, belong to fine thread nut. Fine thread nuts are suitable for high speed rotating or moving parts connection. Because of helix angle is small, they have good anti loosening effect. In addition, they usually are used to adjust axial gap of machine, and can play the role of component trimming. The application place of fine thread nuts include: needing pre tightening force, asking for high precision requirements, compact design, and so on.

In the dustry of fastener producing, blacking means:The workpiece will form a blue or black oxide film on the workpiece surface at room temperature or heating to proper temperature in air, water vapor or chemical solution, so as to improve its corrosion resistance and appearance of surface treatment process.
