💡 What’s the best way to use a miniature coupling for tiny shafts?
When working with small couplings, keep these in mind:

• Always match shaft size closely to avoid misalignment

• Tighten both set screws evenly for balance

• Use a thread locker (like Loctite) if it’s going on a vibration-prone motor

• Check fitment regularly if running high-speed RPMs
