Custom CNC Machined Zinc-Plated Steel Lock Pins for Machinery

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.
