Machining diameter: Ø0.8 mm ~ Ø51 mm
Machining tolerance: ±0.003 mm for copper and aluminum materials; ±0.005 mm for other materials.
Actual tolerances are determined based on customer requirements.
Why Precision Machining Matters for Pin Components
Pins are frequently used as locating references during assembly. Even slight dimensional variation can affect alignment accuracy, assembly repeatability, and structural integrity.
Precision machining helps improve:
- Consistent positioning accuracy
- Better fit between mating parts
- Improved load transfer
- Higher assembly repeatability
- Reduced component replacement during maintenance
Practical examples
- For automated production equipment, accurately machined locating pins help maintain consistent positioning throughout repeated assembly cycles.
- For mechanical transmission systems, precision pins keep moving components properly aligned while minimizing unwanted movement between connected parts.
Material Selection for Precision Pin Components
Different pin applications require different mechanical properties depending on the working environment, loading conditions, and assembly method. Material selection directly affects wear resistance, strength, dimensional stability, and service life.
Other machinable materials, apart from those listed below, are detailed on this page.
Carbon Steel (S15C–S45C) for General Mechanical Pins
For general machinery, carbon steel pins help maintain accurate positioning while supporting repeated assembly and disassembly.
Typical applications include: Locating pins, Assembly pins, Alignment pins, Mechanical fastening pins.
Why it is selected:
- Good machining performance
- Stable mechanical strength
- Suitable for heat treatment
- Cost-effective for production
Chromium Molybdenum Steel and Stainless Steel for Demanding Applications
SCM alloy steel and stainless steel are selected when pins must withstand heavy loads, harsh environments, or long-term operation.
Common materials include:
- SCM415, SCM420, SCM435, SCM440
- SUS303, SUS304, SUS316, SUS420, SUS440C
Typical applications include: Drive mechanism pins, Industrial equipment pins, Structural locating pins, Corrosion-resistant positioning components.
Why it is selected:
- High structural strength
- Excellent fatigue resistance
- Good corrosion protection
- Reliable long-term performance

Surface Treatments for Custom Pin Components
Pin components require stable positioning and reliable load transmission in mechanical assemblies. Proper surface treatment helps improve wear resistance, protect contact surfaces, and maintain consistent performance during repeated movement and assembly.
Other machinable materials, apart from those listed below, can be found on this page.
PVD Coating for High-Wear Pin Applications
PVD coating provides a hard protective layer for pin components exposed to repeated contact, sliding, and mechanical loading.
Passivation for Stainless Steel Pin Components
Passivation is commonly applied to stainless steel pins requiring improved corrosion resistance while maintaining precise dimensions.
Other surface treatment options can be found on this page for reference.
