Carbon Steel ISO 4016-2022 Hexagon head bolts

Hexagon head bolt is a Class C hexagon head bolt with bolt thread specifications ranging from M5 to M64 and a pitch varying from 0.8mm to 6mm. Typically made from carbon steel, its surface is treated with zinc plating, phosphating, or coatings to improve corrosion resistance and service life.
 
Product Characteristics

• Hexagonal head design: easy to use wrenches, screwdrivers and other tools to tighten and disassemble, improve work efficiency.
• Standardized dimensions: The ISO 4016 standard specifies the diameter (nominal diameter) and length (nominal length) of the bolt, such as M10×40 indicates a diameter of 10 mm and a length of 40 mm. This standardized design makes bolts easily interchangeable and versatile.
• Various materials available: Bolts made of carbon steel and alloy steel can be selected according to different application scenarios and strength requirements.
• Good mechanical properties: ISO 4016 standard bolts have clear mechanical performance indicators such as tensile strength, yield strength, elongation and hardness to ensure the reliability and safety of the connection.
• Surface treatment: The standard also specifies the surface treatment requirements of bolts, such as galvanizing, phosphating or coating, etc., to improve the corrosion resistance and service life of bolts.

 
Application
Primarily used in mechanical and structural engineering, it is widely applied across many industries such as automobile manufacturing, aerospace, and construction. Its standardized design makes it easy to install and remove, providing a solid and reliable connection.

• Mechanical manufacturing: Used to connect various mechanical parts and equipment.
• Construction: Used in buildings to join and fix components.
• Automotive industry: Used to connect engine, chassis and other components in the automotive manufacturing process.
• Aerospace: Used in the aerospace industry to connect key parts such as aircraft structures and engine components.
