Bolts for small hexagonal head reaming holes GB27-76 stainless steel (304/316) carbon steel

Small hexagon head bolts for reamed holes are a kind of mechanical parts, mainly characterized by their small hexagonal heads, which are suitable for use in reamed holes. These bolts are usually used for fixing or connecting mechanical parts and need to be used in conjunction with nuts.GB27-76 is a Chinese national standard which specifies the detailed parameters and manufacturing requirements of these bolts.

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: Small hex head design allows bolts to be used in space-constrained environments.

High Torque Carrying Capacity: The hex head design provides a larger area to carry the torque of a wrench or wrench, reducing the risk of slippage.

Precise fit: Reamed holes ensure a tight fit between the bolt and the hole, increasing the reliability of the connection.

Suitable for a wide range of materials: Can be manufactured with different materials, such as carbon steel, stainless steel 304/316, etc., to suit different working environments and corrosion resistance needs.

Scope of application

Mechanical manufacturing: widely used in the process of fixing and assembling in machine tools, automation equipment and other mechanical fields.

Automobile industry: used in the connection of automobile chassis, engine and other parts.

Building structure: Used in the fixing of building structure, such as the connection of steel structure.

Electronic equipment: used in some electronic equipment that requires high reliability connection.

Aerospace: also used in aerospace field due to its high load bearing capacity and reliability.

Quality Certification

Hebei Bentley is ISO9001:2015 certified and equipped with relevant certificates for quality assurance. Due to its specific dimensions and performance levels, it is suitable for a wide range of industrial and commercial scenarios including, but not limited to: machine building, construction work, transport, energy industry, timber frame connections.
