dumpsterCNC Threaded Couplers Advantages: ◊ Connect your stepper motor to the lead screw without needing a lathe to turn down the lead screw shaft. ◊ A flat on the shaft is not needed. ◊ These couplers will not damage the shaft. ◊ Made from high tensile strength Delrin. ◊ Complete with 4 stainless steel #4-40 screws and brass inserts. ◊ Tighten the screws about 1 turn past snug. Do not over tighten, a little torque will clamp these on really tight. For best results, re-tighten after a couple hours of use. |
