Motor Flex Coupler - 5mm x 8mm

Motor Flex Coupler - 5mm x 8mm

These flex couplers are ideal for attaching 8mm threaded rod or lead screw to standard NEMA 17 stepper motors. They feature two grub screws per shaft, so they grip strongly and won't slip!

Flexible couplers are great because they allow for slight misalignments in the coupled shafts - so even if your RepRap isn't perfectly aligned, these couplers will cut you some slack!
