last days I bought some second hand 45 x 45 aluminum profiles. I will build with them new CNC. To connect rails to them I have to use M5 screw. Normal metric nuts are to small, because profiles have 10 mm grove. I checked web and there were some special nut for this. But the prize is so big. For 30 nuts I have to pay more than for 4 m second hand profile. So I decide to made myself one. I measured the T grove in profile, took 20 x 5 mm flat and put it on CNC. And this is what I have:
T shape of this nut holder made it easy to slide inside a grove. Used normal M5 nut made it durability. It can be easy changed to bigger nuts. To compare some old special nut. Prize of it is equal to prize of this 3 that I made.
