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.
