The slide-in T-slot nut is the more robust choice in T-slot nuts. The contact surface between the nut and the T-slot is the biggest of all variants. The slide-in nut has to be inserted into the T-slot from an open side of the profile, and it is not possible to insert the slide-in nut after the T-slot is closed in from both sides. The slide-in nut also doesn’t have the same fixation like the roll-in nut and will slide along the length of the nut by itself. This slide-in nut is meant for the 30- and 40-series profiles and has a M8 thread.
