Carbon Steel Hexagon Socket Set Screws with Cone Point

1. Experience

 As a professional manufacturer of carbon steel hexagon socket sets and screws with cone points, with over ten years of experience in the fastener industry, we are proficient in domestic and international standards such as GB/T 78-2007, ISO 4027, and DIN 914. From raw material intake to finished product shipment, the entire process undergoes rigorous testing—each batch undergoes dimensional accuracy, thread gauge checks, hardness, and tensile strength tests. Our products are widely used in key domestic projects and exported to overseas markets, their quality proven by long-term market experience.

2. Customization

We support customization of non-standard sizes, irregular specifications, and special materials. Customizable parameters include: diameter (beyond M1.6-M24), length (2mm to 60mm and above), material (carbon steel/alloy steel/stainless steel), performance grade (8.8/10.9/12.9, etc.), and surface treatment (blackening/galvanizing/Dacromet/phosphating, etc.). We offer free sampling services, with a fast response time of 3-7 days based on drawings or samples. Flexible minimum order quantities, supporting both small-batch trial production and large-volume purchases.

3. Scale

Our factory is equipped with multi-station cold heading machines, thread rolling machines, heat treatment equipment, and automated production lines. Common specifications are readily available year-round. Multiple surface treatment production lines (blackening line, galvanizing line, Dacromet line) ensure stable delivery times. Ample supply capacity and a direct-from-source production model make our hexagon socket set screws with cone point prices more transparent and competitive.

Carbon steel hexagon socket set screws with cone point are widely used in applications requiring high-strength fastening or special installation conditions:

1. Shaft Fixing: The most typical application of carbon steel tapered-end hexagonal set screws is fixing parts such as gears, pulleys, couplings, and cams to drive shafts. The tapered end embeds into the locating hole or V-groove on the shaft, achieving precise alignment and strong anti-loosening properties, effectively preventing axial movement or relative rotation of transmission components during operation.

2. Precision Machinery and Automation Equipment: Widely used in machine tools, automation equipment, industrial robots, precision instruments, and meters. The headless design ensures a flat surface on the equipment, and the tapered end structure meets the requirements for precision positioning and self-alignment. A high strength grade of 8.8 and above ensures the reliability of connections during high-speed operation.

3. Construction Machinery and Heavy Equipment: Suitable for heavy-duty vibration conditions in mining machinery, metallurgical equipment, crushers, conveying machinery, etc. The 12.9 grade carbon steel tapered-end hexagonal set screws are heat-treated for enhanced vibration resistance and anti-loosening performance, significantly reducing equipment maintenance frequency and costs.

4. Automotive and Transportation: Used for fastening connections in engine peripheral components, gearboxes, transmission systems, chassis, etc. High strength and vibration resistance ensure safe connections in complex road conditions.

5. Electronic and Communication Equipment: Suitable for applications requiring strict surface flatness, such as precision electronic equipment, communication devices, and instruments. Blackened carbon steel tapered-end hexagonal set screws are cost-effective and aesthetically pleasing, making them a common choice for electronic assembly.

6. Construction and Bridges: Used in steel structure connections, bridge bearings, curtain wall fixing, and other engineering applications. Dacromet coating offers excellent corrosion resistance, making it suitable for outdoor high-salt-spray and long-life projects.
