✔️ Holds 6 items, fits 4 to 7 mm shafts, 22 mm length, reliable steel make
This handy kit packs six rigid metal connectors that lock different axle sizes together. Builders rely on these direct clamps to mount stepper drives, DC gears, and micro servo setups in custom robots and desktop CNC rigs. The dual bolt mechanism grips round rods tight without sliding or wobbling. You get a full hardware tray with twenty four machine screws and a dedicated Allen key right out of the box.

💡 Why choose a rigid inline coupler over flexible designs for DC gear motors A locked steel interface keeps power delivery straight while killing wobble from cheap mounts. Here is why this straightforward build wins on the workbench. - Locks driving and driven spindles in perfect alignment for zero slippage during cuts - Takes sharp startup jolts so your gearbox stays protected and runs cooler longer - Holds steady under vibration without loosening up on standard extrusion frames - Tightens down with dual opposing screws to keep dust out and signal clean
