ASME B18.3 American internal cylindrical head hex bolts are a common fastener with a cylindrical head and a hexagonal hole in the center of the head, and are typically installed and removed using an Allen wrench. These bolts are designed to meet both British and American standards and are suitable for a wide range of industrial applications.

Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.

Grade: The product grade is divided into A grade and B grade, as well as different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.

Advantage:

Compact design: cylindrical head design, simple appearance, easy to hide, suitable for space-constrained occasions.

HIGH STRENGTH: Usually made of high-strength steel, able to withstand large torque without slipping or breaking.

Anti-corrosion: The surface is plated, with good anti-corrosion performance.

Variety of sizes: Available in a variety of diameters and lengths to meet the needs of different application scenarios.

Scope of 

application

Mechanical equipment: used for fixing parts in mechanical equipment, such as power tools, machine tools, etc.

Furniture assembly: widely used in the assembly of furniture, such as desks, bookcases, bed frames and so on.

Electronic products: used as fasteners in the shells, brackets and other parts of electronic products.

Building decoration: used to fix metal frames, glass and other materials in decoration works.

Automobile manufacturing: used in the fixing of automobile interior parts, engine parts and so on.
