Allen Bolt Product Describsion
Allen bolts are Befast Fastener’s main product. We are a manufacturer and also a supplier of these bolts. While producing and supplying these bolts, we also produce nuts, washers and other fastener products used in conjunction with them.
These bolts we produce are generally classified according to whether the material is carbon steel or stainless steel. More specific classifications are as follows:
Boltead’s DIN912 stainless steel allen bolt
Boltead’s DIN912 black oxide allen bolt
Boltead’s DIN912 ZP allen bolt
Carbon steel allen bolts are generally classified according to strength levels. The more common strength levels are: 4.8, 8.8, 10.9, and 12.9. Among them, bolts with grade 8.8 or above are generally called high-strength bolts （high tensile bolts）.Stainless steel allen bolts are generally classified according to different materials. The more common stainless steel materials are SUS201 SUS304 SUS316
In addition to different materials and strengths, the biggest impact on allen bolts is surface treatment. The following are the more common surface treatments for these bolts: black oxide, black zinc, zinc plated (ZP), color zinc plating (CZP /YZP), hot dip galvanized (HDG), dacromet coating, etc.
Allen Bolt Production Process
Allen bolts are sent from the raw material line to the final product. They generally go through the following process:
Annealing of raw materials – pickling – drawing – forming – grinding – heat treatment – surface treatment – classification – packaging – shipping
The rough schematic diagram is as follows:

Allen Bolt Application fields
Allen bolts are a commonly used fastener that plays a crucial role in many different applications. The following are some common uses of these bolts.
Mechanical equipment assembly: Allen hexagonal bolts are often used in the assembly process of mechanical equipment. By tightening the Allen bolts, it is ensured that the various components of the equipment are tightly fixed together, thereby maintaining the structural stability and normal operation of the equipment.
Automotive manufacturing: Allen bolts are widely used in automotive manufacturing. The various components of a car, such as the engine, chassis, braking system, etc., require internal allen bolts for fastening. The high strength and stability of allen bolts make them an indispensable part of automotive manufacturing.
Aerospace industry: Allen bolts play an important role in the aerospace industry. The structure of aircraft and spacecraft must be able to withstand high pressure, high temperature, and high-speed loads under extreme conditions. Allen bolts, through their high strength and reliability, can ensure a tight connection between the structure of aircraft and spacecraft, and ensure their safety during flight or space missions.
Construction and Civil Engineering: Allen bolts are widely used in construction and civil engineering. When constructing high-rise buildings and bridges, allen bolts are used to connect and fix different structural components, such as steel bars, beams, and columns. The strength and stability of allen bolts enable building structures to withstand various loads while maintaining their stability and safety.
Electronic and electrical equipment: Allen bolts are also used in the manufacturing and assembly of electronic and electrical equipment. During the assembly process of circuit boards and electrical equipment, allen bolts are used to secure different components and connect circuits. Its high-precision design and fastening ability ensure the normal operation and stability of electronic and electrical equipment.
Furniture manufacturing: Allen bolts are widely used in furniture manufacturing. The different components of furniture, such as the legs of chairs, trays of tables, etc., are usually fastened with allen bolts. By using allen bolts, furniture can be assembled more securely and have better structural stability.
Sports equipment and outdoor equipment: Allen bolts are also used in the manufacturing of sports equipment and outdoor equipment. For example, in products such as climbing equipment, bicycles, and skateboards, allen bolts are widely used to connect different components and provide additional support.
In summary, allen bolts have a wide range of applications in various fields. They play a crucial role in different engineering projects through their high strength, stability, and reliability. Whether in automotive manufacturing, aerospace industry, construction engineering, or furniture manufacturing, allen bolts can meet various needs and ensure the stability and safety of the required structure.
