High Precision Zinc-Plated Steel Lock Pins | Custom CNC Machined
Fasteners for Mechanical Equipment
These zinc-plated steel lock pins are engineered to meet the high
demands of modern mechanical equipment and industrial assemblies.
Manufactured from high-strength carbon steel and finished with
corrosion-resistant blue-white zinc plating, each pin is
custom-machined to provide a precise fit, excellent wear
resistance, and long-lasting durability in challenging
environments.
Our steel pins are commonly used as locating components, fasteners,
or alignment shafts in a wide range of machinery and structural
applications. They are especially useful in assemblies where stable
positioning and repeatable alignment are critical, such as in
automotive systems, automation lines, industrial frames, gear
housings, or heavy equipment.
Each piece is produced through precision CNC turning and milling,
ensuring consistent diameter, clean transitions, and tight
dimensional tolerances. The surface is coated with high-quality
blue-white zinc, offering both a clean, professional appearance and
excellent corrosion protection in indoor and semi-exposed
environments.
The standard size for this model is approximately 50–60mm in
length, with varying diameters and geometries depending on your
technical needs. We fully support OEM/ODM services—clients can
submit their own 2D drawings (PDF/DWG) or 3D models (STEP/IGES), or
even physical samples, and we will replicate or adapt the design
accordingly.
Since our establishment in 2007, our company has been dedicated to
the custom manufacturing of non-standard mechanical components.
With over 17 years of experience, we have developed deep expertise
in carbon steel processing, surface treatment optimization, and
complex part geometries. Our factory spans more than 5,000 square
meters and is ISO9001-certified, ensuring that every batch is
produced with full traceability and strict quality control.
We understand that in B2B manufacturing, lead time and reliability
are just as important as quality. That’s why we’ve streamlined our
production process to deliver fast turnaround—on average, around 14
working days from order confirmation to shipment, depending on the
complexity and quantity.
Our lock pins are widely used by clients in Europe, North America,
Southeast Asia, and the Middle East, where performance, price, and
responsiveness are all critical. Whether you're developing
prototypes, maintaining machinery, or building a high-volume
production line, our team is equipped to support your sourcing
needs with responsive communication, technical expertise, and
scalable capacity.
