Customized Parallel Keys

Customized keys are manufactured based on customer drawings, allowing for tailored dimensions and machining features such as drilled holes, threading, chamfering, or end-face modifications.
Ideal for specialized assemblies, limit positioning, or modular drive systems, they are widely used in high-precision transmission setups and non-standard mechanical designs.

​​

Product Features

• Custom machining available for both ends: drilling, threading, chamfering, and more

• Key body can include anti-slip grooves, center holes, countersinks, or other complex features

• Suitable for shaft-end assemblies, mechanical limit stops, and special torque coupling

• Standard dimensions can be adjusted for specific length, thickness, or material requirements

​​​​​​

Material & Surface Treatment

• S45C (Carbon Steel):
  Can be heat treated (HRC 20–45) for increased torque capacity and wear resistance

• SUS304 (Stainless Steel):
  Corrosion-resistant; suitable for food machinery, electronics, and automation equipment

• SUS316 (Stainless Steel):
  Higher corrosion resistance; ideal for marine, medical, or high-humidity applications

​​​

Size Range

• Width (b): 3mm – 32mm

• Height (h): 3mm – 20mm

• Length (L): Standard or fully customized

• Machining options: Drilling, tapping, slotting, chamfering, surface treatment, etc.

​

Applications

• Custom molds and precision positioning assemblies

• Robotic arms, spindle motors, and shaft drive modules

• Precision components requiring limit stops, quick release, or precision fits

​​​​​

Customization & Notes

• Drawings or physical samples required for quotation

• Supports both batch production and small-lot prototyping

• Flexible adjustments on material, size, and machining to meet design requirements
