This custom carbon steel lock pin with threaded end is a high-strength, precision-machined component designed for securing, aligning, and fastening mechanical assemblies. Manufactured from durable carbon steel and finished with a blue-white zinc plating, this dowel-style pin offers exceptional resistance to corrosion, high tensile strength, and excellent surface protection in demanding industrial environments.
The threaded section allows for a firm, reliable engagement into tapped holes or fixtures, while the smooth cylindrical body ensures accurate positioning and alignment during assembly. Thanks to its standardized geometry and stable mechanical properties, this type of pin is commonly used in a wide range of applications including automotive chassis, industrial equipment, construction hardware, tool assemblies, jigs and fixtures, agricultural machinery, and custom mechanical systems.
The part is processed through CNC turning and milling operations, ensuring consistent dimensional accuracy and surface finish across all production lots. We strictly control tolerances to meet ISO standards and support tight fits (e.g., H7/g6 or H8/f7) as per customer requirements. The final surface is plated with trivalent blue-white zinc, which not only enhances corrosion resistance but also offers a clean, professional appearance.
Threaded lock pins like these are especially useful in situations requiring easy disassembly, torque retention, and resistance to vibration loosening. For applications where repeated installation/removal is necessary, the pin’s threads can be reinforced or customized based on client needs.
Typical dimensions range from 20mm to 80mm in length and 6mm to 20mm in shaft diameter, though we fully support non-standard designs. Customers are welcome to submit drawings (PDF, CAD, STEP) or samples for tailor-made production. Additional options such as partial knurling, cross holes, internal threading, or grooved structures can be added based on your assembly method.
Our factory, established in 2007, is an ISO9001-certified CNC machining supplier based in China, specializing in non-standard part customization. We operate from a 5,000m² facility equipped with over 60 sets of advanced CNC lathes, milling centers, and inspection tools. We’ve delivered millions of precision metal components to clients in Europe, North America, and the Middle East, including OEM/ODM services.
Lead time is typically 14 working days for most custom orders, and we accept both small batch prototypes and volume production. Quality, reliability, and responsiveness are at the core of our service.
