✔️ 1/8 to 0.2in 5mm bore, 1.02in 26mm len, 0.39in 10mm od, alum build

This rigid aluminum shaft coupler links stepper motors, servos, and lead screws to drive mechanical platforms. You will find it handy on CNC routers, plasma cutters, 3D printers, and DIY robot builds where steady torque transfers matter most. You receive a single precision unit complete with four clamp screws and a hex wrench.

✅ Lightweight alloy body handles high rotational speeds without adding weight
✅ Dual clamp holes grab 0.25in to 5mm shafts snugly under load
✅ Fixed link design locks out wobble so axis tracking stays razor sharp

💡 What distinguishes a fixed shaft link from compliant mounts on heavy CNC frames?
Tightening a rigid connector is mighty handy when you need zero flex during aggressive kerf removal.
- Clamp the hex keys flush to eliminate reverse play instantly
- Bore matching stays critical so torque spreads uniform across the grip
- Zero your linear rails first to keep travel vectors snappy on long pulls
