2 Pack 6mm To 6.35mm Bore Rigid Shaft Coupler With Set Screws 14mm Diameter 22mm Length Carbon Steel Galvanized Built Tough Heavy Duty High Torque Motor Connector For 3D Printers RC Boats Cars And Aircraft

2 Pack Rigid Shaft Coupler: 6-6.35mm Bore, 14mm Dia, 22mm L
✔️ 14mm diameter, 22mm length, bore 6-6.35mm, M4 screws

These rigid shaft couplers are designed to connect motors to drive shafts in a range of hobby and industrial setups like 3D printers, robot projects, CNC machines, and model vehicles. Built from galvanized carbon steel, they resist corrosion and withstand high torque, delivering reliable, low-inertia power transmission between shafts.

✅ Total diameter 14 mm (0.55 in) and length 22 mm (0.87 in)
✅ Bore range 6 mm to 6.35 mm (0.24-0.25 in) with M4 set screws
✅ Material: galvanized carbon steel for strong, anti-corrosive performance
✅ Includes 2 couplers per pack, M4 hex wrench, and 8 M4 set screws
✅ High-torque, low-inertia connection for precise motor coupling

💡 What is a rigid shaft coupler used for in hobby CNC and 3D printer builds? This handy piece helps couple motor shafts to drive shafts with precise torque transfer and minimal backlash.

• Transfers torque efficiently between shafts with no backlash
• Fits 6-6.35 mm bore shafts and uses M4 screws
• Maintains alignment under high torque in stepper drives
• Made from galvanized carbon steel for rugged, long-lasting use
