Roll-in T-slot nut, 40-series M6

The Roll-in T-slot nut is our favorite T-slot nut. The nut can be easily rolled into the T-slot, and because it has a ball with a spring inside of the nut, it is fixated into place. The Roll-in T-slot nut will not fall down the T-slot. Furthermore, the Roll-in T-slit nut is self-aligning so the thread will always be in the middle of the T-slot. This Roll-in T-slot nut is compatible with the 40-series profile and has a M6 thread.
