dumpsterCNC Threaded Couplers
◊ 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.
