Motor Flex Coupler - 5mm x 8mm

Motor Flex Coupler - 5mm x 8mm

These flex couplers are ideal for attaching 8mm threaded rod or leadscrew to standard NEMA 17 stepper motors. They feature two grub-screws per shaft, so they grip strongly and wont slip!

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